xkbcommon: Converting keysym to keycode

[adlo]

afaict there’s a for loop that iterates over all the layouts, and within that it iterates over all the shift levels, and within that it iterates over all the modifier masks? Is that what’s going on? So basically it’s iterating over them until it finds a match?

In that printf on line 220, would the value of “keycode” at that point be the best approximation of XKeysymToKeycode ()?

What’s the difference between shift level and modifier state? They seem to overlap somewhat. Is it that the Shift key can be both a modifier and a shift level, but the Num Lock key is a shift level but not a modifier?

It calls xkb_keymap_key_get_mods_for_level(), which seems to be related to getting the mods, and it seems to have things that get the name of a key, or get a key from the name, but I can’t see anything that looks like it’s related to getting or approximating a keycode from a keysym.
