a couple of shorcuts à la Rhinoceros

[newyd_cnc]

Hello,

I find a couple of keyboard shortcuts particularly helpful in Rhino that perhaps could be considered useful for QCad/CAM too:

1- in order to specify the origin 0,0 point, just key 0 + Enter (zero + enter): saves typing the comma and second zero. Also consider that on some keyboards typing 0 requires pressing a shift key (french azerty keyboard for instance ...)
2- add the possibility of using the caracter 'r' as an alternative to '@' to specify a relative (incremental) position: as a matter of fact on some keyboards the '@' caracter requires a combination of altGr + key to obtain; the caracter 'r' on the other hand is super direct to obtain. I am not suggesting to suppress the @ for relative position specifying, but just to add the possibility of using 'r' leaving the choice to he user

thank you for considering these ergonomic ideas to speed up some keyboard work

Same here but I use my numeric keypad at the right side for entering the values. (Desktop PC)

Question: How often are you required to enter the origin as coordinate?

I think that entries without a Cartesian or Polar separator are not recognized as a valid coordinate (see code)
If the string wasn't split into 2 parts and equal to zero then RMath.parseCoordinate() can not return RVector.null.
Zero + Enter must be reserved for entering a zero value. As distance, angle, radius, ... (see Code)
And then Zero + Enter is zero away from the current relative zero.

You could set the relative zero fixed at (0, 0) for this purpose ...
... Loosing the key functionality of it.

The origin is easily located and addressed in a wider zoom state, it is a red cross with a pixel based size.
Typically with Auto-Snap active this is a Grid-Snap.


Something else than the character '@' is configurable.
See menu Edit .. Application Preferences .. General .. Coordinate Format
There are but 4 options to choose from.
I can tweak the config file in direct to use an 'r', although not advisable and then not listed as a new or custom option.

Remind that an 'r' stands for rads (as suffix).
