Hi Val,

Like Pilou mentioned, Esc for unselect (also turns off points).

For selecting all curve objects, you can make a keyboard shortcut with this as the command:
script:moi.geometryDatabase.getObjects().getCurves().setProperty( 'selected', true );

> *shortcut for reselect

Could you explain some more about what this one would do?

If you make a mistake when selecting things, you can use undo to go back to the previous selection, is that it?
