Sorry, My mistake.
This is for the test version available on the website not version
0.0.19.
Also the letters a,c, and x can be entered into a text field if they
are the first character entered. After that they perform their
function key role.
For instance, typing minnesota can be done only my typing the 'a',
moving to the left of the letter then typing 'minnesot'. If you try
to type it straight through once you get to 'minnesot' pressing the
'a' key highlights all the previous text.
