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