Pressing ctrl-E will enter a special paste mod
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.
