You may scroll up or down through the commands you entered previously by pressing the up or down arrows. You can also jump to the last command begining with a letter by pressing <cntl> + <shift> + that letter.
<cntl> + <shift> + F (find the last command beginning with "F")
Zoom Shell also supports some of the C Shell ways of accessing the command history: !! repeats the last command, !3 repeats the third command in the history list, and !di repeats the last command begining with di. Type history to view your command history.
Zoom Shell saves the last 50 commands from session to session. If you wish to change that number, type history and a number:
history 0 (the history is cleared out each time)history 200 (the last 200 commands are saved each time)
history 50 (the default)
The history list is kept in a file instead of in memory, so that different Zoom Shell windows can share it. Since it is not in memory, it does not increase memory usage to make the list long. It can, however, slow down scrolling through the list. The history list will grow as long as Zoom Shell is running. The list is only cleared out when the first Zoom Shell window starts up.
