 425
 426   DIFFERENCE FROM THE ORIGINAL TIBKEY:
 427
 428     1. Vowel 'a' should be typed explicitly by the key 'A'.
 429        This is really inconvenient. But to make the coding
 430        scheme clear, it is desirable to have an explicit
 431        vowel sign for 'a'.
 432     2. Tsheg is assigned to SPC key. You can input a space
 433        by typing '>'.
 434     4. To avoid the default stacking \e$(7$B\e(B and to obtain \e$(7"#"B\e(B,
 435        type 'E' instead of 'v' (=\e$(7"B\e(B).
 436     3. There are many characters that are not supported in the
 437        current implementation (especially special signs). I hope
 438        I'll complete in a future revision.
