weird ripple cut behavior

I've been cutting a short piece in 16.2.7 using UHD pro Res originals in an HD timeline. I had to make a lot of ripple cuts which I was doing using the shortcut <shift command X>, after first setting my in and out points with the letters 'i" and "o".
This worked for me but only after I got used to some inconsistently odd behavior. It seemed like most often the first time I hit that shortcut , it would make some other ripple cut that would cut a lot more footage than i intended. I never figured out exactly what it was doing, because I quickly learned if I hit command Z to undo the first ripple cut and then hit the shortcut <shift command X> again , the Ripple cut would be made properly. Sometimes I would have to undo 2 incorrect operations and the 3rd would be right. Very bizarre.
Any idea what might be going on here?

My guess would be that you also have other clips selected. You can have an In-to-Out range set and still have individual clips selected at the same time. (You'd use this for looped playback of a range, etc.) So I'm thinking you have some other clips selected and Ripple Cut is cutting them, and when you undo they come back but the clips aren't selected anymore. So you're next Ripple Cut is acting only on the In-Out range.

I never figured out exactly what it was doing

There's no need to reinvent the wheel here, no need to "figure things out". You can learn how the software works.

wfolta,
I'll bet you're right . That makes some sense as i never was watching out for it and always selecting the timeline to mark my in and out points in the clips rather than the timeline. Also explains why when I tried it again on another timeline just to test I couldn't repeat the problem. Thanks - If you're right, posting this might save me a lot of headaches in the future.

I can reproduce what you're talking about, I think.

I select In and Out. The timeline darkens outside of the In Out. Then I select a clip outside of the In/Out and it highlights red and the rest of the timeline is no longer darkened. (The gray bar representing In-to-Out is still above the timeline, but it is no longer a region of brighter display with the rest of the timeline darkened.) If I Ripple Delete, it deletes the highlighted clip and the rest of the timeline outside of In-Out darkens.

If I Undo, the clip comes back, it's not highlighted red, and the timeline outside of In-Out is darkened. If I do Ripple Delete, it deletes from In to Out.

If you're not zoomed out far enough to see outside of In-Out, you might not notice whether the rest of the timeline is shaded or not, which is your clue as to whether the Ripple Delete is going to take place in the In-Out region or for something else.
