*
* We could do something outright absurd, like using gtk_accelerator_name
* followed by gtk_accelerator_parse to normalize the key press, but the
* performance impact of that makes it feel like a bad plan.
*
* So if it's an alpha character, make a lower case version, and check the
* binding against that as well.
*
* Note: isalpha's argument is an int, however it is documented that it
* must be either an unsigned int, or the constant EOF.
*
* Notably, it segfaults for some values above 0xFF on my system.

*
* For the first case, a text URI, we must use vte_terminal_check_match_at

* For the key binding case, we'll need to find the current location of the
* pointer.
*
* For the mouse binding case, we'll be passed the location the click
* happened.

* For the menu case, we recorded the location of the pointer at the time
