In attempting to answer sinbad's question, I figured it was the
perfect opportunity for i_CTRL-\_CTRL-u which is described as "like
CTRL-O but don't move the cursor". So I created a mapping:

:inoremap ~ <c-bslash><c-o>gUB

yet if I insert "This is a test~" (expecting it to change it to
"This is a TEST" with the cursor where it started after "test") it
changes where my insertion point is. Are others seeing this too?
Is this a bug or my misunderstanding of i_CTRL-\_CTRL-u?

PS: to the OP, you can use

:inoremap <f4> <esc>gUiwgi

which is just these 3 bits together:

:help gU
:help iw
:help gi
