CTRL-I no longer splits clips in 2.3?

Hello – I just updated my Audacity software to 2.3.

I can no longer split a clip by using the CTRL-I command. I can still split by navigating to Edit > Clip Boundaries > Split.

Is the shortcut gone? Anything I can do to get it back?

The number of default shortcuts has been trimmed down to free up a few key combinations for custom shortcuts.
The “full” set of shortcuts is still available, but it has to be enabled in Preferences:
“Edit menu > Preferences > Keyboard: Defaults => Full”
See: https://manual.audacityteam.org/man/keyboard_preferences.html

Or if you don’t want the full set - you could add back the CTR + -I as a custom shortcut.
