Simple, Practical, and Common - 33612 entries

Simple things we do all the time should be able to be done with very few keystrokes, but sometimes I find something I need to do makes me go, "There MUST be a better way." This challenge is just a simple movement and entering text at a certain place.

comment and uncomment code inline - 1122 entries

It's very useful to be able to comment out a block of code in a quick edit. And likewise to uncomment the code. This operation often involves multi-line stanzas and even large blocks. With just line-wise navigation and insert mode this would cost you about 4 keystrokes per line. Master this hole of VimGolf and you'll quickly drop your key count in day to day Vim as well.
