Very true, vim always amazes me. The learning is always there which keeps
it ever interesting.
As for the above issue, "folds" are good too.
- goto just before start of function and: zfgg
- after end of function: zfG
To prevent search from opening folds:
:set foldopen-=search
For running commands that skips closed folds
:foldd {cmd}
