I have downloaded and installed Darktable 3.0 and have been learning about it for awhile now primarily from the online manual. I really like the program so far, especially the fact that it tells me when it's working on the image when there is a delay needed to process (I could never really tell when it was done using RawTheropee, especially on small adjustments). Anyway, there's lots more to learn and it has some features that I will probably never use, however, I've run into a bit of a snag and hope someone here might be able to help. My problem is that I want to zoom in and out on my active work image and for the life of me haven't been able to figure out how. The manual states that I should use "Middle Click" to zoom to 1:1, "Double Middle Click" to zoom to 2:1 and use mouse scrolling and the control key to zoom from 2:1 to 10:1 (the manual actually says 1:10, but I think that's a misprint). My obvious problem is that the laptop I am using only has a touch pad and the left and right mouse buttons. Is there a simple way to get around this and/or simulate a middle click or mouse scrolling or do I have to install a mouse and driver that has these options and/or upgrade my computer? Any feedback would be appreciate! Good luck and good shooting to all.

Ctrl++ and Ctrl+- should work while in darkroom for that purpose.

Personally, I think it would benefit you to get a mouse. Once you dive into Drawn and Parametric masks, you will appreciate having a little more control.

Usually the trackpad driver has a way to configure "middle-button" functionality. In the past I used three-finger click for that for example.

I would purchase an appropriate mouse in any case.
It will give you better control than you get with a touch-pad.

Nice one! I just tried it in darktable on my laptop and it works with the "two finger" drag method.

Thank you! The Ctrl++ and Ctrl+- will have to do for now, but I am currently looking into adding a full function mouse to my current laptop and agree that it's addition would be the best overall and long term solution.
