vim jj
The letter j is a sad letter. It hardly ever gets pressed in a row like that.
Map "jj" to switching into command mode in vim and make j a happy letter.

Copy & Paste Trick
Often you have hash keys in strings that you may need to copy many times. This can be cumbersome but thanks to vim, it's actually a fairly....efficient (correct diction?) process. Put your cursor anywhere on the string that represents the hash key and press ci' (notice the single quote at the end).
This stands for change inside some character like ' or < or { or [ etc. Now that deleted it so just go back to command mode, put your cursor wherever you want to paste and press either p or P.
Period to Repeat
Erm very ambiguous title haha. **Press the "period" on keyboard to repeat last command in Vim.** @@ for "colon-commands".
Vim Tabs
I never knew you could vim tabs in the command line! It is in the terminal so it's basically just ascii art and shading but you can interact with it using your mouse! (if you have "set mouse=a" in your vimrc)
vim -p firstfile secondfile
Switch with the mouse or the command gt
