Keyboard re-mapping (key binding)

AXIS doesn't pay attention to jog keys with modifier keys pressed
because this had some bad interactions with using the numeric keypad as
digits in MDI mode.

You can put magic incantations in the file ~/.axisrc that customize the
jog keys and also get rid of this behavior of ignoring the key if a
modifier key is pressed.

Here is an example which changes the keys that jog the active axis, and
the keys that jog the A axis:

# -- cut here

---

# Bind ; and ' to jog active axis
root_window.bind("<semicolon>", commands.jog_minus)
root_window.bind("<apostrophe>", commands.jog_plus)
root_window.bind("<KeyRelease-semicolon>", commands.jog_stop)
root_window.bind("<KeyRelease-apostrophe>", commands.jog_stop)

# Bind ( and ) to jog axis 3 (0=X, 1=Y, 2=Z, 3=A, 4=B, ...)
root_window.bind("<parenleft>", lambda e: jog_on(3, -get_jog_speed(3)))
root_window.bind("<parenright>", lambda e: jog_on(3, get_jog_speed(3)))
root_window.bind("<KeyRelease-parenleft>", lambda e: jog_off(3))
root_window.bind("<KeyRelease-parenright>", lambda e: jog_off(3))
# -- cut here

---

To edit your ~/.axisrc file, open a terminal window (Applications > Accessories >
Terminal). Then type "gedit .axisrc". Paste the lines above into the file,
then click save, then close the application.

The next time you run emc, the settings in the .axisrc file will take effect.

To edit it again, just do the same thing: "gedit .axisrc" in the
terminal.

If you want to use different keys, here's how to figure out what to use instead
of "parenleft" and so on: In the terminal, type "xev". A new window
will pop up. Click on it, but keep an eye on the terminal window. When
you press a key, it will print several lines of information on the
terminal. The one that matters is this one:
state 0x0, keycode 34 (keysym 0x5b, bracketleft), same_screen YES,
^^^^^^^^^^^
that keysym string is the one to put in your .axisrc file.
