Replay mode
Time mode
You can quickly jump back to the instant in time just before a command began executing using the [ c [?] and ] c [?] bindings.
Copy mode
When the cursor is on the output of a command in copy mode, the command itself is shown in replay mode's status bar at the bottom of the screen.
Just like in time mode, you can also jump between commands using [ c [?] and ] c [?].
You can also quickly select the complete output of a command using [ C [?] and ] C [?].
