fine.","startTime":244210,"duration":2000,"startOfParagraph":false},{"content":"I'm going to show you a few random tips and

cool.","startTime":249890,"duration":5440,"startOfParagraph":false},{"content":"Just a few random things I'm going to go through.","startTime":255330,"duration":3610,"startOfParagraph":true},{"content":"The first thing is text objects, and there are a few commands around text

seminar,","startTime":261700,"duration":3310,"startOfParagraph":false},{"content":"but for example, let's say I spelled my name wrong,

it.","startTime":278900,"duration":2150,"startOfParagraph":false},{"content":"Similarly, if I want to change something inside quotes there's also a command for

in.","startTime":290260,"duration":1970,"startOfParagraph":false},{"content":"You can do everything from the keyboard, whatever it is.","startTime":292230,"duration":9770,"startOfParagraph":false},{"content":"Or alternatively, let's say I have this image tag inside this anchor tag.","startTime":302000,"duration":4430,"startOfParagraph":false},{"content":"Have you guys covered HTML in class yet?","startTime":306430,"duration":1730,"startOfParagraph":true},{"content":"Yeah, so maybe I want to delete this tag,","startTime":308160,"duration":2410,"startOfParagraph":false},{"content":"which normally what you have to do is you have to use your mouse","startTime":310570,"duration":2510,"startOfParagraph":false},{"content":"and carefully highlight exactly what you want to delete and delete it.","startTime":313080,"duration":2960,"startOfParagraph":false},{"content":"But in Vim that's simply dit, and you can delete it out really quickly,","startTime":316040,"duration":5280,"startOfParagraph":false},{"content":"and I'll explain to you what all those commands mean and how you use them in a second.","startTime":321320,"duration":6700,"startOfParagraph":false},{"content":"Another example, I have some code here,","startTime":328020,"duration":2300,"startOfParagraph":false},{"content":"and let's say I want to indent the code, but I want to indent the code","startTime":330320,"duration":3320,"startOfParagraph":false},{"content":"just within the parentheses, and I can also indent the code using 3 commands","startTime":333640,"duration":6300,"startOfParagraph":false},{"content":"using basically >iB.","startTime":339940,"duration":5420,"startOfParagraph":false},{"content":"Another thing that's really cool about Vim is something called visual block editing.","startTime":345360,"duration":4600,"startOfParagraph":false},{"content":"I don't know if you guys have ever wanted to highlight","startTime":349960,"duration":2420,"startOfParagraph":false},{"content":"a rectangular block of text in your code sometimes","startTime":352380,"duration":3310,"startOfParagraph":false},{"content":"instead of having to do this weird sort of line thing that spans all different lines.","startTime":355690,"duration":4880,"startOfParagraph":false},{"content":"For example, in Vim you can do that.","startTime":360570,"duration":1880,"startOfParagraph":false},{"content":"I can highlight rectangles like this, which is pretty cool, ","startTime":362450,"duration":2810,"startOfParagraph":false},{"content":"but furthermore, I can edit using that functionality.","startTime":365260,"duration":2690,"startOfParagraph":false},{"content":"For example, if I want to give some sort of prefix to all of our names","startTime":367950,"duration":4100,"startOfParagraph":false},{"content":"I can highlight a block and then add something.","startTime":372050,"duration":6050,"startOfParagraph":false},{"content":"Similarly, I can also highlight this block and choose to delete it,","startTime":378100,"duration":3960,"startOfParagraph":true},{"content":"or maybe I'll highlight this block and change it to D because we're all doctors.","startTime":382060,"duration":4240,"startOfParagraph":false},{"content":"Whatever it is, you can do all those different things.","startTime":386300,"duration":3130,"startOfParagraph":false},{"content":"Finally, folding is really cool. ","startTime":389430,"duration":1840,"startOfParagraph":false},{"content":"A lot of IDEs have this where you can fold different functions out of view","startTime":391270,"duration":2570,"startOfParagraph":false},{"content":"in case you don't want to see them.","startTime":393840,"duration":1750,"startOfParagraph":false},{"content":"For example, suppose I have this bunch of text here, and I don't really want to see it.","startTime":395590,"duration":4530,"startOfParagraph":false},{"content":"I want to keep it out of view because I'm editing something else in the file.","startTime":400120,"duration":2590,"startOfParagraph":false},{"content":"I can fold it up so it's all collapsed,","startTime":402710,"duration":7870,"startOfParagraph":false},{"content":"and that way it's out of view, ","startTime":410580,"duration":1570,"startOfParagraph":false},{"content":"and I can edit other things that are on the page, and this is really great.","startTime":412150,"duration":2160,"startOfParagraph":false},{"content":"You can fold up functions and whatnot or fold up classes when you're programming ","startTime":414310,"duration":3240,"startOfParagraph":false},{"content":"just to keep them out of view when you're not editing them,","startTime":417550,"duration":1830,"startOfParagraph":false},{"content":"and later when you want to see them you can open them up.","startTime":419380,"duration":4950,"startOfParagraph":false},{"content":"And you can see it just opened everything up.","startTime":424330,"duration":4930,"startOfParagraph":false},{"content":"Tabs, buffers, and windows.","startTime":429260,"duration":1960,"startOfParagraph":false},{"content":"Vim is pretty cool in that","startTime":431220,"duration":2040,"startOfParagraph":false},{"content":"normally in a lot of text editors you can only edit one file at a time,","startTime":433260,"duration":3020,"startOfParagraph":false},{"content":"like in Nano, or maybe if you're using Notepad or Gedit.","startTime":436280,"duration":2680,"startOfParagraph":false},{"content":"I've actually never used Gedit very much, but at least in Notepad++","startTime":438960,"duration":2510,"startOfParagraph":false},{"content":"you can have tabs, but Vim has the concept of tabs, buffers and windows.","startTime":441470,"duration":5230,"startOfParagraph":false},{"content":"For example, you can open up a bunch of new tabs.","startTime":446700,"duration":2060,"startOfParagraph":false},{"content":"You can see here at the very top I have now a bunch of tabs,","startTime":448760,"duration":3030,"startOfParagraph":true},{"content":"and I can close them.","startTime":451790,"duration":2560,"startOfParagraph":false},{"content":"Furthermore, there's this concept of buffers,","startTime":454350,"duration":3200,"startOfParagraph":false},{"content":"which is the idea that once you've opened a file","startTime":457550,"duration":2560,"startOfParagraph":false},{"content":"it stays alive in the buffer, and if you want to navigate to that file really quickly","startTime":460110,"duration":3800,"startOfParagraph":false},{"content":"you can navigate to it really quickly within the buffer as well,","startTime":463910,"duration":2380,"startOfParagraph":false},{"content":"and furthermore, within one pane you can also split your window up into multiple windows.","startTime":466290,"duration":5600,"startOfParagraph":false},{"content":"For example, if I want to split this window up into multiple windows","startTime":471890,"duration":4000,"startOfParagraph":false},{"content":"you can see right here that I can have the same code twice,","startTime":475890,"duration":4190,"startOfParagraph":false},{"content":"and I can split more and more and more, and right now it doesn't look that good","startTime":480080,"duration":3720,"startOfParagraph":false},{"content":"because by default I have the default window size be kind of big","startTime":483800,"duration":3540,"startOfParagraph":false},{"content":"so all the others are squashed out,","startTime":487340,"duration":2150,"startOfParagraph":false},{"content":"but normally when I'm on my computer and not on this projector","startTime":489490,"duration":2510,"startOfParagraph":false},{"content":"I can have several panes open at the same time, which is really nice for ","startTime":492000,"duration":3920,"startOfParagraph":false},{"content":"editing multiple files at the same time.","startTime":495920,"duration":5530,"startOfParagraph":false},{"content":"You can also  have things like select and replace,","startTime":501450,"duration":2350,"startOfParagraph":false},{"content":"and we'll actually cover that in the seminar,","startTime":503800,"duration":4100,"startOfParagraph":false},{"content":"so I'll skip that for now.","startTime":507900,"duration":1350,"startOfParagraph":false},{"content":"You can also interact with the command line in all sorts of different ways.","startTime":509250,"duration":2789,"startOfParagraph":false},{"content":"For example, if I have some sort of list here and I want to sort it—","startTime":512039,"duration":4341,"startOfParagraph":false},{"content":"I don't know, let's add another fruit, grape,","startTime":516380,"duration":6659,"startOfParagraph":false},{"content":"and I can highlight this using the highlight function ","startTime":523039,"duration":2411,"startOfParagraph":false},{"content":"and call sort, and it will sort it automatically for me.","startTime":525450,"duration":3530,"startOfParagraph":false},{"content":"Similarly, if you're going to be editing CSS, which I presume you probably will be doing ","startTime":528980,"duration":3170,"startOfParagraph":true},{"content":"for your final project, most people do, ","startTime":532150,"duration":2040,"startOfParagraph":false},{"content":"and maybe you want to keep your CSS organized by sorting them in alphabetical order.","startTime":534190,"duration":6010,"startOfParagraph":false},{"content":"You can also highlight them and call sort, and it will sort them for you.","startTime":540200,"duration":4210,"startOfParagraph":false},{"content":"These are some of the examples of the things that Vim can do,","startTime":544410,"duration":2970,"startOfParagraph":false},{"content":"and you'll notice that the key thing that I really want to draw your attention to","startTime":547380,"duration":3380,"startOfParagraph":false},{"content":"is that I'm doing everything from the keyboard,","startTime":550760,"duration":3980,"startOfParagraph":false},{"content":"and if you are able to see where my hands are placed","startTime":554740,"duration":3280,"startOfParagraph":false},{"content":"you'll also see that my hands never really move from the home row.","startTime":558020,"duration":3190,"startOfParagraph":false},{"content":"Normally when you're editing text you usually have to use a mouse","startTime":561210,"duration":3580,"startOfParagraph":false},{"content":"and click around and whatnot, and that sort of movement drags you down","startTime":564790,"duration":3240,"startOfParagraph":false},{"content":"and wastes time, or perhaps you're moving between the home row and the arrow keys,","startTime":568030,"duration":4250,"startOfParagraph":false},{"content":"and so you're moving back and forth like that, which is a bit cumbersome ","startTime":572280,"duration":3340,"startOfParagraph":false},{"content":"but also slows you down, and the thing is once you get really good at Vim","startTime":575620,"duration":3130,"startOfParagraph":false},{"content":"everything you want to do is done without having to move your hands","startTime":578750,"duration":3600,"startOfParagraph":false},{"content":"from the home row, which is great.","startTime":582350,"duration":8380,"startOfParagraph":false},{"content":"Hold on, I'm going to open up this application. There we go.","startTime":590730,"duration":4140,"startOfParagraph":false},{"content":"Now you can see what commands are running down the lower right window.","startTime":594870,"duration":3450,"startOfParagraph":true},{"content":"All the functions that I just showed you are things that are included by default with Vim,","startTime":598320,"duration":4870,"startOfParagraph":false},{"content":"but there's also a huge number of plugins that you can also use","startTime":603190,"duration":3630,"startOfParagraph":false},{"content":"to improve your Vim experience.","startTime":606820,"duration":1570,"startOfParagraph":false},{"content":"If you downloaded the configuration files that I included,","startTime":608390,"duration":2150,"startOfParagraph":false},{"content":"and there are instructions on how to install them in the PowerPoint","startTime":610540,"duration":2610,"startOfParagraph":false},{"content":"and also in the email I sent out, I have about 40 plugins installed","startTime":613150,"duration":4690,"startOfParagraph":false},{"content":"or maybe 30 plugins, and every single one","startTime":617840,"duration":2650,"startOfParagraph":false},{"content":"brings additional functionality to Vim that improves your Vim experience.","startTime":620490,"duration":3510,"startOfParagraph":false},{"content":"For example, one of my favorites is something called surround.vim,","startTime":624000,"duration":2960,"startOfParagraph":false},{"content":"and it basically allows you to work with surrounding ","startTime":626960,"duration":2800,"startOfParagraph":false},{"content":"or delimiting characters much more easily.","startTime":629760,"duration":2440,"startOfParagraph":false},{"content":"One example, I don't know if you guys ever code in LaTeX,","startTime":632200,"duration":3760,"startOfParagraph":true},{"content":"but LaTeX is a math typesetting language that is used to make","startTime":635960,"duration":2870,"startOfParagraph":false},{"content":"really nice looking math, and whenever you want something to look like math","startTime":638830,"duration":4120,"startOfParagraph":false},{"content":"you wrap it in dollar signs, and let's say I'm typing some equation  like F=ma,","startTime":642950,"duration":4100,"startOfParagraph":false},{"content":"and I forgot to wrap it in dollar signs.","startTime":647050,"duration":2190,"startOfParagraph":false},{"content":"Then I can highlight this and wrap it in dollar signs just like that.","startTime":649240,"duration":9030,"startOfParagraph":false},{"content":"Alternatively, Vim allows you to delete things inside tags","startTime":658270,"duration":5370,"startOfParagraph":false},{"content":"and delete tags and whatnot, but Vim by nature","startTime":663640,"duration":3660,"startOfParagraph":false},{"content":"doesn't allow you to change tags, so for example, I have this div tag,","startTime":667300,"duration":3100,"startOfParagraph":false},{"content":"and I want to upgrade to HTML5 and use a new header tag.","startTime":670400,"duration":2660,"startOfParagraph":false},{"content":"I can do change surrounding tag and type in header,","startTime":673060,"duration":9230,"startOfParagraph":false},{"content":"and it will automatically change that for me.","startTime":682290,"duration":4250,"startOfParagraph":false},{"content":"Similarly, let's say we have something in parentheses,","startTime":686540,"duration":3080,"startOfParagraph":false},{"content":"and I wanted to change that from parentheses into brackets or something like
