Oddly enough, I think in nearly 15 years of using this moniker, you're the first to notice that connection! :)

I think you can simplify this further. First, 1s is unnecessary, s on its own defaults to replacing only the first occurrence of a pattern (you need the /g flag to change that behavior) and like most commands operates on the current line only by default (you need a range larger than 1 to change that behavior).

The movements you're doing may also be a bit overkill, depending on the situation precisely; if you simply match on GUICreate instead of the 200 it will probably narrow the results to one of a few calls (since GUICreate isn't something I would expect to be called massively often) - then just use the /gc flag to confirm which ones need substitution over the whole file (or most of it).

Finally, \zs can simplify your substitution. It lets you define where the match actually starts *after* some other matching. So, Give this a go:

%s/^GUICreate.*, \zs200/$K_MAINGUIWIDTH/gc

Just hit 'y' or 'n' a few times as relevant.


Hope it helps!
