Browsing Maithili translation

* Translators, the strings in the “keyboard label” context are
* display names for keyboard keys. Some of them have prefixes like
* XF86 or ISO_ — these should be removed in the translation. Similarly,
* underscores should be replaced by spaces. The prefix “KP_” stands
* for “key pad” and you may want to include that in your translation.
* Here are some examples of English translations:
* XF86AudioMute - Audio mute
* Scroll_lock   - Scroll lock
* KP_Space      - Space (keypad)
