1. *editor mode*: a terminal-based code editor is opened and the resulting code is executed once you save and exit
   - `cry`... edit code in Vim... code runs.
1. *file mode*: code within an existing .cr file is copied to a tmp file for editing and run once editor is closed.
   - `cry scripts/stuff.cr`
1. *back*: open and previous run in editor mode.
   - `cry -b 1` ... copies previous run to tmp file for editing and runs when editor is closed.
1. *loop*: continuously edit and execute code.
   - `cry -r -b 1` ... copies previous run to tmp file for editing and runs when editor is closed in a loop.
1. *log*: show a log of all previous runs.
