Version 1.8.4                                    Mon Sep 25 2023                      minput_event_to_key(3m17n)

       Convert an event to an input key. The minput_event_to_key() function returns the input key corresponding
       to event event on frame by a window system dependent manner.

       In the m17n-X library, event must be a pointer to the structure XKeyEvent, and it is handled as below.

       At first, the keysym name of event is acquired by the function XKeysymToString. Then, the name is
       modified as below.

       If the name is one of 'a' .. 'z' and event has a Shift modifier, the name is converted to 'A' .. 'Z'
       respectively, and the Shift modifier is cleared.

       If the name is one byte length and event has a Control modifier, the byte is bitwise anded by 0x1F and
       the Control modifier is cleared.

       If event still has modifiers, the name is preceded by 'S-' (Shift), 'C-' (Control), 'M-' (Meta), 'A-'
       (Alt), 'G-' (AltGr), 's-' (Super), and 'H-' (Hyper) in this order.

       For instance, if the keysym name is 'a' and the event has Shift, Meta, and Hyper modifiers, the resulting
       name is 'M-H-A'.

       At last, a symbol who has the name is returned.
