simplekeycodes.nim

# Simple non-full-screen example that prints out keycode enums of the keys
# pressed on the keyboard.
#
# Note that although echo, write and the terminal module should not be used
# when using illwill in fullscreen mode, in non-fullscreen mode it's okay to
# use them. In such case illwill is typically used for non-blocking keyboard
# input only, so it's best to import only the functions needed for that, as
# shown below. This way there will be no symbol name clashes when importing
# the terminal module (e.g. the foreground and background color enums).
