Simple Table for IBus

It's easy as 0, 1, 2!

0. Install this package

1. Create a text file that looks like this:

   [trigger]
   trigger = \\
   
   [combining-map]
   ` = U+0300
   ' = U+0301
   ^ = U+0302
   ~ = U+0303
   
   # bar above
   _ = U+0304
   
   # breve
   ( = U+0306
   
   # dot above
   . = U+0307
   
   # diaeresis
   : = U+0308
   
   # ring above
   o = U+030A
   
   # double acute
   " = U+030B
   
   # reverse hat
   v = U+030C
   
   # cedilla, ogonek
   , = U+0327;U+0328
   
   [arbitrary]
   # right arrow
   -> = U+2192
   rarrow = U+2192
   
   # left arrow
   <- = U+2190
   larrow = U+2190
   
   # Squared
   ^2 = U+00B2
   
   # Registered trade mark
   (r) = U+00AE
   (R) = U+00AE
   
   # Copyright
   (c) = U+00A9
   (C) = U+00A9
   
   # Smiley face
   sm = U+263A
   :) = U+263A
   
   # Frowny face
   :( = U+2639
   fr = U+2639
   
   # Heart
   <3 = U+2665
   
   # Checkmark
   ch = U+2713
   

2. Use it via Choose Map File and you can type \:) to get ☺ or \o: to get ö.

In the course of your normal typing, nothing will happen until you type the trigger \. If you want to type an actual \, just hit Enter afterwards. If you think there's a character that you use even less often than \ then you can specify it as the trigger in the trigger section above.
