Well, in a few words, I can say: launch the program and learn by using it. It is very simple and full of tips. Most of the buttons have some tip showing what they will do. If you have to compile, please read the INSTALL file. And also, specific libs you have to install (on Debian): - libgtk-3-dev - libcurl4-dev - intltool - libtool See also the web site: http://klavaro.sourceforge.net - COLORS Some colors may be configured through the file preferences.ini There you should create a session named [colors] and set some colors with the internet/html syntax (#RRGGBB). Example: [colors] key_fg=#332200 key_1=#112233 key_9=#213243 text_intro_fg=#222222 char_untouched_bg=#fffaf8 char_wrong_fg=#880000 char_correct_fg=#009900 char_retouched_fg=#bbbbaa cursor_blink_bg=#ff88ff The preferences.ini file holds all the default key/value pairs, since the first time when the application is run. But they are never overwritten after that, so direct edition should be done by the user to change the colors. Here is the complete list of keywords to set colors: Background and foreground for the tutor introductory texts: text_intro_bg text_intro_fg Background and foreground for the tutor texts before they be typed out: char_untouched_bg char_untouched_fg The same for the tutor texts after they be correcty typed out: char_correct_bg char_correct_fg Same for tutor texts after they be wrongly typed: char_wrong_bg char_wrong_fg Same for tutor texts after they be correcty retyped, correcting errors (only in fluidity module): char_retouched_bg char_retouched_fg Blinking color of the block cursor in the tutor tests: cursor_blink_bg cursor_blink_fg Foreground of keys in the virtual keyboard: key_fg Background of keys, according to the finger responsible for it, from left to right (key_5 is valid for both thumbs, it is the space key): key_1 key_2 key_3 key_4 key_5 key_6 key_7 key_8 key_9 - GOALS And also, the goals for touch typing skill may be configured in preferences.ini file. They give the limits for each tutor module, so the user is told when he/she should go to the next level. They also appear as horizontal lines in the progress charts. The default key/value pairs used in the application show up after the first time one runs and close it gracefully, take a look at your preferences.ini file. - LEVELS These are similar to the goals above, but they are used only to distinguish the comments done by the tutor after each practicing session, along all the modules. With them, the program knows how the user is doing with his training, and then suggests more directions to take. As with GOALS, see your preferences.ini file, after launching and using the application for at least one time.
