Changing case in Vim

Is there a command in Vim that changes the case of the selected text?

3 Answers

Visual select the text, then U for uppercase or u for lowercase. To swap all casing in a visual selection, press ~ (tilde).

Without using a visual selection, gU<motion> will make the characters in motion uppercase, or use gu<motion> for lowercase.

For more of these, see Section 3 in Vim's change.txt help file.

See the following methods:

 ~ : Changes the case of current character guu : Change current line from upper to lower. gUU : Change current LINE from lower to upper. guw : Change to end of current WORD from upper to lower. guaw : Change all of current WORD to lower. gUw : Change to end of current WORD from lower to upper. gUaw : Change all of current WORD to upper. g~~ : Invert case to entire line g~w : Invert case to current WORD guG : Change to lowercase until the end of document. gU) : Change until end of sentence to upper case gu} : Change to end of paragraph to lower case gU5j : Change 5 lines below to upper case gu3k : Change 3 lines above to lower case 

gUaw : Change all of current WORD to upper.
