Visual Mode Increment
In Vim patch 7.4.754, I noticed Vim now supports incrementing numbers in Visual mode. You can increment numbers by pressing
CTRL-A, and decrement with
CTRL-X. It's one of those features that doesn't sound amazingly useful but can be handy once you've memorised it. If you build off Vim's master branch you can try it out now.
To enter Visual mode, type
CTRL-V (technically Visual mode blockwise). You can then use
hjkl to select multiple lines, and increment the numbers on each line with
CTRL-A. I thought this might be good for shifting sets of numbers in a numerical list, like you might find in a Markdown file for example.
