- Ctrl-A on a blank line will enter raw REPL mode. This is like a permanent paste mode, except that characters are not echoed back.
- Ctrl-B on a blank like goes to normal REPL mode.
- Ctrl-C cancels any input, or interrupts the currently running code.
- Ctrl-D on a blank line will do a soft reset.
- Note that ctrl-A and ctrl-D do not work with WebREPL.
