A Kitten Dies Every Time You Use Scroll Bars
« on: 2019 August 07 10:35:26 »
If you want to consider yourself an intermediate/advanced PixInsight user, please don't use scroll bars (on a regular basis) to navigate image windows.

There are two ways to perform a temporary switch to Pan mode:

- Press the spacebar key and hold it down, then click the primary mouse button on the image and drag.

- Click the middle mouse button on the image and drag.

Both methods are much faster and more accurate than using scroll bars, plus you can navigate in both plane directions at the same time.

In similar ways, you can:

- Use the mouse wheel to zoom in/out the image.

- Use Ctrl + mouse wheel to zoom in/out centered at the current cursor position on the image.

- Use Ctrl+spacebar to switch to Zoom In mode temporarily. In this mode you can define a rectangular area to approximate the area of the image that will be zoomed in the view.

- Use Ctrl+Alt+spacebar to switch to Zoom Out mode temporarily.

On macOS, replace Ctrl with Cmd in the above list.

So let's save those kitties, please, especially when you record a video!

Thanks very much for this. Does this all also work with a trackpad on a MacBook?

Yes, spacebar + drag works fine on an Apple trackpad. Note that in this case you don't have to click, just press space bar and move your finger on the trackpad. Of course, you can also pinch with two fingers on a trackpad to zoom in/out.

Lest we forget the equally noble cursor Pan Mode via Alt+P. :-)
Best always, Warren
