doncolga . . . I think my favourite Sonar tools may be the keyboard shortcuts that I use frequently:
D (maximize / minimize multi-dock)
Shift-F (fit project tracks to window)
Shift-G (snap to beginning of a clip)
Control-TAB (toggle between Track View and Console View)
G (Go to time)
. . . and then for features there's:
Event Inspector
Channel Tools
Bounce To Clips
Pro Channel
Quick Groups
. . . am I only allowed five ?
