EDIT: /* Seems I was a bit too fast on pressing 'n' that it was printed during the loading screen, thus not at it's 'regular' position.. but just check the return number Smilie */

It even has a 'fallback' mode, using '+' and '-', just in case anything with possible translations should not work.

And the best part, you dont have to press enter - at least not as long your 'read' does support this feature Smilie
Well, the 2nd part is what I'm going to adapt now.

But first I'll write a quick 'help handler' and probably prepare a dyanamic 'man(page) handler' as well.

But if you're interest in the BASIC version, it's first iteration (without the actual handling of the different read abilities , here's the code:
Code:
	ask() { # "What question?"
	# Ask a yes/no question, returns 0/true for yes and 1/false for no
	# y/n are taken from language file and are used in code
		# Check if 'yesno' is empty, if so, fill with fallback values
		[[ -z "${SWARM_MSG_ASK_YES}${SWARM_MSG_ASK_NO}" ]] && \
			SWARM_MSG_ASK_YES="+" && \
			SWARM_MSG_ASK_NO="-"

		swarm.print.border -e
		# Print the text
		$PRINTF "$(swarm.print.goto $(( ${#SWARM_THEME_DATA[border-left]} + 2  )))$1 (${SWARM_MSG_ASK_YES}${SWARM_MSG_ASK_NO})"
		# Move the cursor
		$PRINTF "$(swarm.print.goto $(( $COLUMNS / 2 * 2 - ${#SWARM_THEME_DATA[border-left]} - 2  )))"
		read -n1 answer
		$PRINTF "$posEND\n"

		case "$answer" in
		"+"|"$SWARM_MSG_ASK_YES")
				return 0
				;;
		"-"|"$SWARM_MSG_ASK_NO")
				return 1
				;;
		*)		return 1
				;;
		esac
	}

Lets share the code as long it's simple Smilie
