The shortcut scheme follows a simple model: Cmd works at the gem (project tab) level, Cmd + Ctrl works at the shard (session) level, and Cmd + D / Cmd + Opt handle split panes.
Gems (project tabs)
Shortcut
Action
Cmd + T
New gem
Cmd + W
Close gem (or the focused pane when split)
Cmd + 1-9
Jump to gem by position
Cmd + Shift + ]
Next gem
Cmd + Shift + [
Previous gem
Shards (sessions within a gem)

Cmd + Ctrl + T

Cmd + Ctrl + W

Split panes
Shortcut

Cmd + D changed in v2.75.0. In older versions it made a new shard, now it toggles a split pane. To make a new shard, use Cmd + Ctrl + T.
Terminal
Shortcut
Action
Cmd + K
Clear screen and scrollback (keeps the shell prompt)
Cmd + F
Find in scrollback
Cmd + +
Increase font size
Cmd + -
Decrease font size
Cmd + 0

Cmd + Ctrl + F

Cmd + Y

Cmd + Shift + C
Copy selection
Cmd + Shift + V
Paste
Cmd + click
Open a file path or URL under the pointer
Cmd + Y opens a chat-style view of the agent conversation for the focused shard, read from the transcript rather than the terminal renderer — handy for reading and driving the conversation without the TUI.
Cmd + F opens a find bar over the terminal. Type to search, Enter / Shift + Enter jump to the next / previous match, a count shows how many matches were found, and Esc closes the bar.
Cmd + K and Cmd + F are claimed by crystl at the app level (the same way iTerm and Warp claim them), so they won’t reach the program running in the terminal.
Facet inserts
Shortcut
Action
Cmd + Opt + 1
Fire the facet insert bound to bar slot 1 into the active shard
