While editing text, we often need to grab the Eyedropper tool to pick some formatting or color for the selected range from another object. An instinct whispers 'Press I key' — and it obviously but often unexpectedly replaces the range with the 'I'. Undo!
Then me might think of pressing Alt — and it does temporarily switch to Pan — which is cool and useful, since you can’t hit space.
We need a modifier to temporarily switch to Eydropper.

...but all modifiers are taken (except fort Ctrl+Shift, which swithes input languages if you have several for some users) and Ctrl+Alt+Shift (which is too long to be a viable solution).

What if we change the behavior of pressing Shift while in editing text mode? Most probably nobody needs to create new text object with vertical orientation while editing a text, right? Let’s use Shift for temp switching!
