backspace does not delete vehicle restrictions as advertised

[kianzarrin]

the hint in the picture above says backspace should reset vehicle restrictions but when I press backspace nothing happens.
when I press delete it resets everything.

@kvakvs I remember you wrote some code about this?

[kvakvs]

I wrote keyboard shortcuts code and probably touched code which checked Delete/Bkspace.
Many months ago. It is literally one IF operator.

[kianzarrin]

so should backspace reset rules or not? we need a unified policy.

On Macbooks, Delete button does not exist. They have Backspace, and to press Delete, you must hold Fn and Backspace, hence for convenience we supported both keybinds for one function. Both should work, at least on Mac. Windows users do not care.

With vehicle restrictions and parking tools, there's no segment selection - so which segment does delete/backspace apply to?

Would need something like speed limits where there's a button to switch to eraser mode (or 'reset to default' to use speed tool terminology).

There was an idea about having an eraser button on main toolbar, but that would be icky in relation to any tools that have segment/node selection or their own UI which already has delete button.

Another option is that, without UI panel, del/backspace could switch to 'eraser mode' which would change mouse cursor to an eraser with OSD/tooltip explaining to user what to do (ie. click stuff to reset it). Right-click/Esc could potentially exit the eraser mode.

Edit: With respect to eraser mode (where mouse cursor changes), that could also be introduced to tools that use segment/node selection when no segment/node is selected. (if a node/segment selected, del/backspace just resets that selected item). Also, with the eraser mode, shift key (etc) could be used to apply erasing along a route / between junctions / etc.
