6.1 keyboard bindings

+The same default menu file is used in all GUI HIDs. It comes with multi-stroke +key bindings, plus only a very few, alternative keys that use modifiers +(mostly ctrl). A multi-stroke key binding requires the user to type in a +sequence of keys, e.g. pressing 't' and 'l' (written as {t l} in this document) +will make pcb-rnd switch to the line tool. There are two major advanatges of +using multi-stroke instead of modifiers: +

It is often easier to remember them, e.g. the above {t l} can be + memorized as 'tool, line', and it is similar to {t a} for 'tool, arc' + and {t, p} for 'tool, polygon'. The old menu file had these as F2, F3 + and F6. They could be also ctrl+l, ctrl+a, ctrl+p, but then if another + group of functionality required similar letters, like l for list or + p for print, they would ned to use a different modifier, e.g. alt+l + and alt+p. At the end there would be a random set of alt, ctrl, shift + combinations that are real hard to remember - this is exactly how + the old (pre-2.0.0) default menu file was. +
Since pcb-rnd is a graphical CAD, the mouse is an inportant user input + device. Most users will have one hand constantly on the mouse. It is much + faster to type a sequence of 2 or rarely 3 plain keys with one hand than + doing the acrobatics for something like ctrl+t or even alt+shif+u. +

+Most multi-stroke keys, especially the commonly used ones, use two strokes. +Some rarely used feature will require three. The system can be regarded +as a tree: e.g. in a 3-key sequence, starting from the root +(nothing is pressed) the first key select a chapter, the second +key narrows it down to a subchapter and the third key (leaf) selects the actual +action within the subchapter. The current key tree is: +
