It would be handy to keep Ctrl+Enter for confirmation and jumping to the next unconfirmed segment [or the action set in Preferences], and e. g. Alt+Shift+Enter dedicated for jumping to the next segment.
• There is only one dedicated shortcut for segment confirmation and jumping. Ctrl+Enter can be configured in Editor Preferences to jump either to the next segment or the next unconfirmed segment (+ other options).
Available workaround (if any):
• No quick workaround (pressing down arrow multiple times (then Home) is inconvenient; changing the preferences just for a single jump action isn't worth the effort)
• Besides keeping Ctrl+Enter for the action set in Preferences, a second confirm+jump hotkey, e. g. Alt+Shift+Enter should be dedicated for jumping to the next segment [or another action configurable in Preferences].
