vim: gU and gu in one map
dictionary, lowercase, uppercase, vim
Solution
If you're trying to invert case, you can use `~`. Normally this works only on the selection (e.g. visual mode), but if you want it to be more useful, then `:set tildeop` so you can do `~w` or whatever movement command you like.
Problem
in vim, with ``` gUw ``` make the word uppercase, with ``` guw ``` make the word lowercase. how I can convert in one map the upper to lower and the lower to upper?
