Mouse Navigation shortcut confusing

I find the "mouse navigation" feature introduced recently both very useful, and very annoying on the mac.

I find it annoying because I very often (eg : every 10 min) confuse the pressing of the mouse +CMD with the activation of a keyboard shortcut.

Let me explain.

When I want use "double click" to select an entire word then copy it with CMD+C,
I almost always start pressing the CMD modifier while double clicking.

Then BAM!, the editor activates mouse navigation, instead of selecting the word.

Well, OK, this is due to the fact I am a bit in a hurry when programming :/
But I've faced this problem for one month now... And I am still unable to adapt my intuitive behaviour.

Suggestion is:
⇒ let the user select a modifier to activate mouse navigation (eg: ALT + clic, or CMD + right clic...)

Also, when deactivating mouse navigation, CMD+DoubleClick does not behave like DoubleClick (ie : it first selects the entire word, then deselect it on mouse release).
This should be fixed.
