Hi,
in terminals, the application interacts with text streams (0 stdin, 1
stdout, 2 stderr, and optionally others with higher numbers) so all
you can get is text (including control characters). You can find
documentation here
https://docs.factorcode.org/content/article-streams.html . You should
be able to write a program to solve
https://rosettacode.org/wiki/Keyboard_input/Obtain_a_Y_or_N_response
from https://docs.factorcode.org/content/article-stream-examples.html
for example.
This is very mature.
To work with keyboard key codes (which can represent modifiers like
control or alt) in the terminal, you need a more general library.
Factor has ncurses bindings which look like it should work on windows
mac and linux: https://docs.factorcode.org/content/vocab-curses.html
if that's what you're looking for.
To work with keyboard key codes in a graphical window, you can use the
UI support in the library:
https://docs.factorcode.org/content/article-ui.html and more precisely
https://docs.factorcode.org/content/article-ui-gestures.html and
https://docs.factorcode.org/content/article-keyboard-gestures.html .
You can get a feel of what kind of event you can receive by running
the run-gesture-logger from extra/gesture-logger/gesture-logger.factor
. Here's the output from a short session I just did:
(random pressing keys on my keyboard and moving the cursor with the
focus on the the black window opened by factor to have focus on it:
T{ key-down }
T{ key-up { mods { A+ } } }
lose-focus
gain-focus
lose-focus
gain-focus
T{ key-down }
T{ key-up { mods { C+ } } }
T{ key-down }
T{ key-down { sym "A" } }
T{ key-up { sym "A" } }
T{ key-up }
T{ key-down }
T{ key-up }
T{ key-down { sym "D" } }
T{ key-up { sym "D" } }
T{ key-down { sym "A" } }
T{ key-up { sym "A" } }
T{ key-down }
T{ key-up }
T{ key-down { sym "RET" } }
T{ key-up { sym "RET" } }
T{ key-down { sym "BACKSPACE" } }
T{ key-up { sym "BACKSPACE" } }
mouse-enter

Hope that helps, feel free to ask more questions !
Cheers,
