The the main method to control openTZT is by keyboard. It's also the only method that provides all (except for clip scratching and BPM dragging) functionality. So openTZT is basically a keyboard controlled program. It is recommended to use a full 101 keys keyboard since the num pad plays a major part in using the effects. Laptop users who have problems with the slightly different keyboard layout should try the keyboard_lang=ENG_LAPTOP option in the tzt.ini (read section "Configuration" for further details).
For better and easier work with openTZT, you should get a grasp of it's basic idea of using the keyboard to control a video performance. You should think of the keyboard as the keys of a piano, then your performance becomes a real performance. You "play" openTZT like a music instrument. But it's a lot easier to learn than a music instrument.
The main idea is to have groups of keys for different functions, like the letter keys basically for
choosing clips and effects, the number keys for parameters and speed and the function keys to select
a palette of clips, effects or presets. With the control keys (Shift, Ctrl, Alt) you tell openTZT
which function you actually want to use.
Now check the table below, you can see that the most effects stuff is in colums Left CTRL and Right CTRL. There are other interesting things to find in this table.
Hinweis für deutsprachige Anwender: Um openTZT mit einer QWERTZ Tastatur vernünftig bedienen zu können, sollte die Option keyboard_lang in der tzt.ini auf keyboard_lang=GER gesetzt werden.
The following table shows the combination of standard keys (ABCDE ... 1234 ... F1 F2 F3 ...) with the openTZT control keys (Ctrl, Shift, Alt). If there are more than one key listed in one of the blocks in the left column, this means the whole range of keys is used for that particular function (like 1 to 9 for nine different playback speeds)

The following sections will show the keyboard assignments like this: A B LShift+4
This means a feature uses a group of keys consisting of the "A" for one function, the "B" for another function and the left "Shift" and "4" pressed together for a third function. In case of Shift (no leading L or R), both Shift keys can be used for this shortcut. Some features also use three keys pressed together. (LCtrl+LShift+4 sets value 2 of the left effect)
Even though many funtions can used by mouse, there are some major functions that cannot controlled by mouse (e.g. activating multiple players). On the other hand, some functions can controlled solely by mouse like clip scratching or BPM dragging.
It's also possible that using the mouse slow's down the program a little (only after clicking) since the calculation where a mouse click has occured is more complex than recognizing the key that has been pressed.
