Pattern UI - keyboard shortcuts

[yaxu]

It could be nice to have keyboard shortcuts for numbered patterns. Ideas:

• Alt-n - toggle mute/unmute pattern
• Shift-Alt-n - toggle solo/unsolo pattern
• Ctrl-n - jump cursor to pattern - creating it if it doesn't exist (for this it would be nice if p4: surrounded by whitespace was equivalent to p4: silence)
• Ctrl-Alt-Shift-n - append .jux(rev)

would be nice to implement this by modifying the code to actually add '_' to the labeled statement, so that the code stays in sync with the playback state
