# Lahu keyboard symbols for X
## Description
Unicode version 5.1 provides the characters to represent the tones of Lahu (and
Ahka). They are currently:
```
/ ˉ / high rising U+02C9 MODIFIER LETTER MACRON
/ ˇ / high falling U+02C7 CARON
/ / mid (no marking)
/ ˬ / low falling U+02EC MODIFIER LETTER VOICING
/ ˍ / very low U+02CD MODIFIER LETTER LOW MACRON
/ ˆ / high checked U+02C6 MODIFIER LETTER CIRCUMFLEX ACCENT
/ ꞈ / low checked U+A788 LETTER LOW CIRCUMFLEX ACCENT
```
The low checked tone was previously using U+F1E7 (and many used U+02F0 before
that) but the current U+A788 has been accepted into Unicode for this specific
purpose.
## Installation
Place the keyboard script in your local xkb search path at
`$HOME/.xkb/symbols/lhu` and then reference it at X startup. This is one way to
do it:
```
setxkbmap -I$HOME/.xkb -option grp:shifts_toggle,grp_led:scroll "us,th,lhu" -print | xkbcomp -I$HOME/.xkb - $DISPLAY
```
This loads the US, Lahu and Thai keyboard maps and allows toggling them via the
two Shift keys. The scroll lock indicator is used to indicate a non-default map.
## Usage
The low tone marks are on the keys for '[', ']', and '\' and the high marks are
on '{', '}' and '|' (Shift'ed keys of low tones). The original characters can be
obtained by using the Ctrl key in as well.
