TilEm data files
----------------

Symbols: these files are fairly self-explanatory; each line contains a
symbol name followed by a hex value.  x3syms is for the 83, x6syms for
the 86, x7syms for the 73.  All versions of the 83+ use xpsyms.

Keys: these files define the key bindings.  x3keys defines the keys
for all versions of the 83 and 83+.  x6keys defines the keys for the
86, x7keys for the 73.

The first field is a GDK key name (without the GDK_ prefix) -- you can
find these in gdkkeysyms.h.  Note that these keys include both
modifier keys and normal character-generating keys.

The second field is a comma-separated sequence of TI scancode names
(without the sk prefix.)  Note that there should be no space between
the scancodes, only a comma.  If the given sequence consists of a
single scancode, the calculator key will remain pressed as long as the
PC key is held down.  Sequences longer than one are timed, starting
from when you first press the PC key; the time when you release the PC
key is irrelevant in this case.
