How to use

Besides the use with the mouse, also the key-board can be used.

I.e. you can make a writing training by writing the sign to be learned with the right hand and check the correct value with the space-bar and later confirm with Z or X, if you knew that sign correctly.

These characters are defined:

Z Character not known

X Character known

A Character not known (same function as Z)

S Character known (same function as X)

R return/back to last character
