Failed escape sequences are not yet played back in their entirety; only an
ESC (ASCII 0x1b) will be seen by the application.
The shift key is only indicated in conjunction with mouse button presses. If
e.g. shift is used to generate a capital letter 'A', **id** will equal 'A', and
shift will be **false**. This should be fixed in the future.
The Shift key is only indicated in conjunction with mouse button presses. If
e.g. Shift is used to generate a capital letter 'A', **id** will equal 'A', and
**shift** will be **false**. This should be fixed in the future.
When Ctrl is pressed along with a letter, the letter will currently always be
reported in its uppercase form. E.g., if Shift, Ctrl, and 'a' are all pressed,
this is indistinguishable from Ctrl and 'a' without Shift. This should be fixed
in the future.
Ctrl pressed along with 'J' or 'M', whether Shift is pressed or not, currently
registers as **NCKEY_ENTER**. This will likely change in the future.
