Vim Tips & Tricks

Writing code

Ctrl+n or Ctrl+p: Autocomplete ;)
]p: Just like p, but it automatically adjusts the indent level of the pasted code to match that of the code you paste into. Try it!
%: Putting the cursor on a brace, bracket, or parenthese and pressing % will send the cursor to the matching brace, bracket, or parenthese. Great for fixing parse problems related to heavily nested blocks of code or logic.
>>: Indent the highlighted code. (See the earlier section about efficient text selection. If no text is selected, the current line is indented.)
<<: Like >>, but un-indents.
gd: Go to the definition (or declaration) of the function or variable under the cursor.
K: Go to the man page for the word currently under the cursor. (For instance, if your cursor is currently over the word sleep, you will see the man page for sleep displayed.)
