It's useful to be able to synchronize scrolling through two files, especially for comparing two files that have too many intraline differences.
Vim supports this, with this annoying incantation:
vim -O oneFile anotherFile -c "windo set scrollbind" -c "windo set scrollopt+=hor" -c "windo set nowrap" -c "windo set cursorbind"
Switch between the windows with: ctrl-w ctrl-w
Nowrap is useful because otherwise different sized lines don't display nicely.
Other annoying things:
- The documentation can't decide what this feature is called, scroll binding or scrolling synchronously.
- Gvim doesn't seem to support cursorbind.
Though maybe vimdiff is actually better for most similar use cases. It gets the defaults right, and with gvim it seems to get cursorbind right too.
