TomeNET

(3.9c) Disabling or using CapsLock and NumLock as macro keys (POSIX only)       
-------------------------------------------------------------------------
There might or might not be a way to do this on Windows too, but for now,
here is a way on POSIX (Linux/Mac OS X) to use your CapsLock and NumLock keys
as actual keys in TomeNET instead of it just being a useless modifier keys.
Or you could just disable CapsLock so it won't interfere if you accidentally
fat-finger it in the heat of battle.

This utilizes the command 'xmodmap' which is usually provided by either the
package x11-server-utils or bash-completion.
xmodmap allows remapping a key and combinations of this key getting pressed
together with modifier keys (shift, alt, etc).

You need to figure out the key code of the key to modify and the available
modifier keys:

  xmodmap -pm
will list all the all modifier keys on your system.
  xmodmap -pke
will list all currently defined keybinds. Grep it to see what capslock and
numlock are currently bound to, so you can restore them afterwards.

On my system the keycode for capslock is 66 and for numlock 77. Verify this
via 'xmodmap -pke | grep Caps_Lock' and 'xmodmap -pke | grep Num_Lock'.
The results of these commands will also be important for restoring the keys'
behaviour afterwards.
They should read:
  keycode  66 = Caps_Lock NoSymbol Caps_Lock
  keycode  77 = Num_Lock NoSymbol Num_Lock
but might also turn out differently, depending on your system, for example:
  keycode  66 = Caps_Lock ISO_Next_Group Caps_Lock ISO_Next_Group Caps_Lock
               ISO_Next_Group Caps_Lock ISO_Next_Group

We see at least three 'columns', as in the first example these are 'Caps_Lock',
'NoSymbol' and then 'Caps_Lock' again.
The first column is the key pressed on its own, the second together with the
Shift key, after that it can depend on your system, see further down in this
chapter for details.

Now you could disable capslock like this, simply by setting it to NoSymbol:
  xmodmap -e "keycode  66 = NoSymbol NoSymbol NoSymbol"
...then run TomeNET, and afterwards restore capslock with
  xmodmap -e "keycode  66 = Caps_Lock NoSymbol Caps_Lock"

Or you could reconfigure numlock to actually become a normal key, by mapping it
to some key that you usually don't use, especially in the specific combination
with a modifier key:
  xmodmap -e "keycode  77 = acute grave period"
...run TomeNET, afterwards restore numlock to normal:
  xmodmap -e "keycode  77 = NumLock NoSymbol NumLock"

Depending on your system you can specify a larger number of modifier-affected
key definitions than just the 3 'columns' in these xmodmap-keycode-commands.
The meaning of the columns are, quoting from the xmodmap man page:

"Up to eight keysyms may be attached to a key, however the last four are not
used in any major X server implementation. The first keysym is used when no
modifier key is pressed in conjunction with this key, the second with Shift,
the third when the Mode_switch key is used with this key and the fourth when
both the Mode_switch and Shift keys are used."

This usually translates to:
  Key
  Shift+Key
  mode_switch+Key
  mode_switch+Shift+Key
  AltGr+Key
  AltGr+Shift+Key
but unfortunately can also turn out differently depending on your system,
especially on laptops. Sometimes the mode_switch key is the AltGR key.
Also, despite the man page saying "up to eigth" some systems might have
more columns even, usually with non-western keyboard layouts.

Note that CTRL is not present. Control cannot be remapped this way, if you
want to use it, you'd have to remap the left and/or right ctrl key itself
first to another shiftkey such as mode_switch, and then map keys to to that
combo of mod_switch and the key you wanted to press together with CTRL.
The obvious drawback is that this will disable ctrl being actual ctrl on your
system while the remapping of ctrl to mode_switch (or whatever other shiftkey
is active).

(A sometimes tool useful for reading key codes is 'xev' from 'x11-utils'.)
