我只是意外地将Vim中的文件转换为全小写。 发生了什么？

Question

There's a ton of camelCase methods and variables in this template (PHP/Smarty), and through some glitch or blunder on my part I just automagically converted them to all lowercase. What gives? I'm now stuck coverting all of these back to the way they were before by hand

Answer 1

I'll guess that you had a block selected in visual mode, and hit u. With a visual block selected u converts the selection to lower-case (U converts the selection to upper-case).
