The image in the main window is controled by CONTROLS and by COMMANDS . This page contains description of garlic controls.

Garlic controls are reserved keys, which may be used to rotate and translate the structure, to change the position of slab surfaces and to change the way color depends on distance from the observer. At present, the reserved keys are numeric keypad keys and four function keys (F1, F2, F3 and F4).

Numeric keypad Function keys

For each control, five steps are available: normal, large, very large, small and very small. If you press the control without holding a modifier key (shift, alt or control), the normal step will be used.

Modifier keys may be used in combination with reserved keys to select large, very large, small or very small step. Here is the table of modifier keys:

MODIFIER KEYS STEP EXAMPLE
none Normal
shift Large
alt_shift Very large
control Small
shift_control Very small

Be sure to avoid ctrl_alt combinations, because some of these combinations may have a very interesting effect (try, for example, ctrl_alt_del or ctrl_alt_F1).
The table below contains the list of controls and corresponding action upon the structure which is currently handled (held, catched). The table refers to PC (101/102) keyboard. There are slight differences between PC and terminal keyboard; three terminal keys are listed in the table (KP_F2, KP_F3, KP_Separator). If you have some exotic keyboard, use the program xshowkey to check the mapping of keys and send this list to the author: zucic@garlic.mefos.hr
