Now that tracks can become so big in renoise and with extras such as the matrix and advanced edit open, I think the following shortcuts would be useful:
Move/jump to first column in track
Move/jump to last column in track
With a 12 column track possible in renoise + fx columns, a track width can easily extend past my 19in TFT width .
Fabio’s explanation sounds like pretty dedicated shortcuts to me and you already personalized your own set, could you rephrase your description of “prefered dedicated shortcuts”? As it seems your current question is already being answered thoroughly or we simply don’t get the clue.
If this doesn’t get added for you it should be one of the easiest things in the world to do with scripting. Making macros of actions then assigning them a shortcut key. Well at least I’m hoping so anyway…
