After setting up some splits/vsplits and resizing gvim or the console running vim, splitter positions are not updated. Is there a way to force updating splitter positions (by retaining them in the same relative position, say split at 50% of the current view)?
CTRL+W is all things splits:
CTRL+W,+- enlarges the current split panel
CTRL+W,-- shrinks the current split panel
CTRL+W,=- evens the split panels size
CTRL+W,CTRL+W- moves the focus to the next split panel
