+# Vim Cheat sheet
+
+This is a little Vim cheat sheet with thing people generally don't seem to be particularly familiar with when it comes to Vim.
+This is about Vim, not NeoVim, but I most things with still apply to NeoVim.
+
+## Self-explanatory things
+These are a few bindings that I don't feel require an extensive explanation.
+
+| binding | action |
+| --- | --- |
+| Z Z | write and quit; equivalent to :wq |
+| Z Q | quit; equivalent to :q! |
+| :x | write and quit; equivalent to :wq |
+| g u | swap characters to lower case |
+| g u u | swap characters to lower case on current line |
+| g U | swap characters to upper case |
+| g U U | swap characters to upper case on current line |
+| g {j,k} | if the current line you're on spans more then the width of your screen, go down to the portion that's past the linebreak |
+| ~ | toggle case |
+| z g | add word to current dictionary |
+| [ s | highlight previous misspelled word |
+| ] s | highlight next misspelled word |
+| z = | open spelling suggestions based on current dictionary and highlighted word |
+| . | repeat last modify operation |
+| ; | repeat last move operation |
+
+## Splits and Terminals
+You can split your vim window with somewhat Emacs-like chords by default; I don't bother changing them because I use with quite a few different computers, not all of which have my Vim dotfiles installed.
+
+| binding | action |
+| --- | --- |
+| C-w s | Horizontal split |
+| C-w v | Vertical split |
+| C-w {h,j,k,l} | Move focus to split {left,down,up,right} |
+| C-w S-{h,j,k,l} | Move split to {left,down,up,right} |
+
+Another usefull thing I don't see a lot of people do is open a terminal session in vim.
+This can be really quite useful if you quickly need to change or check something.
+You do this with the `:terminal` command.
+In Vim, this will horizontally split your current window and open a terminal session in the top half.
+(Yes, you can also open Vim sessions in these terminal sessions if you feel like it).
+You can navigate to and from it just like any other splits.
+In NeoVim terminals are handled significantly worse and is the main reason I went back to base Vim.
+
+## Tips
+
+Something I came across some time ago is that you can interpet the current line with whatever you want using
+```
+:.!<interpeter>
+```
+So for instance running...
+```
+:.!bash
+```
+...while highlighting the line...
+``` bash
+echo Line{1..5} | sed 's/ /\n/g'
+```
+...will result in:  
+```
+Line1
+Line2
+Line3
+Line4
+Line5
+```
