Not handling control characters as expected in prompt/question mode

[dansimau]

First thing I did after typing "Is this thing on?" was to send the ANSII escape sequence to clear the line, but it didn't clear.

Key	Expected result	Actual result
CTRL-U	Clear the current line	Nothing happened
CTRL-A	Move cursor to beginning of the line	✅
CTRL-E	Move cursor to the end of the line	✅
CTRL-→	Move cursor forward one word	Moves cursor forward two positions
CTRL-←	Move cursor back one word	Moves cursor forward two positions
CTRL-↑	Nothing	Prints line one line above (corrupts display)

This are the common ones I use daily but there are many that people might be using, e.g.:
