I've added new keyboard shortcuts in the default menu file: ctrl+arrow
keys will scroll. I've also added {j hjkl} and {k hjkl} cursor movements
because some small keyboards won't have arrows. Plus multi-key bindings to
left and right click on the drawing area.
These, together with our other keys make pcb-rnd somewhat usable even
without any kind of mouse/touchscreen. The multi-key bindings (instead of
heavy use of shift, ctrl, alt or even combinations of them) makes it much
better on tiny keyboards.
Here's a short summary on the most important keys for a no-mouse setup
with the main window drawing area:
- zoom: {z e}, {z z}, {z x}
- grid: {g b} and {g f} do the same as {[} and {]} and there's also {g d}
and {g h} to double or halve the grid
- scroll: ctrl+arrow keys or j then h, j, k, or l
- move the cursor: arrow keys and shift arrow keys or k then h, j, k, l
- left click: {enter} or {k space}
- right click (context menu): {k r}
- change layer: key 1..9 (I plan to make the layer key binding more
configurable)
- change tool: F1..F9 or t then a tool-specific letter (e.g. {t l} for
line)
- menu: {F10}
- invoke the command line: the {:} key or {w c}
Hitting anyting precisely without mouse: the trick is to use the grid;
especially if you have the [ and ] keys available, you can rapidly change
between preconfigured grid sizes. For getting somewhere approximately, use
a rough grid, when you get close to the target refine the grid so you can
go in smaller step. You can also rely on snapping.
(I've just fixed a bug in Cursor() for grid based stepping that is used
with the arrow keys: it is now really stepping grid point by grid point,
unless you press shift)
Note: all these key combos have a variant that takes more key presses but
works on a limited qwerty (e.g. 3 or 4 row where you won't easily have
punctuation or F-keys)
Note: when you don't have arrow keys, plain hjkl can not be used, because
we can't have single-character key combos in the default menu file, those
would shadow off two large parts of the key tree.
