a few shortcuts i can't find (swap clips, trim in or out)

Hello,

There are a few operations that i'd like to do with a single shortcut:

-swap clips on the timeline.

Lets say i have 2 clips on the timeline, the second is selected. Now i'd like to swap it so that the second becomes the first. I know that i can drag while holding alt/ctrl. But thats not what i want, i'm really trying to avoid using the mouse here.

-''select nearest edit point as trim in/out'' - but in ripple mode (yellow trim icon)

This is almost doing what i want, but this operation doesn't ripple the edit by default. I know about the shortcut to toggle trough the trim modes, but that requires another few shortcuts (which is by default a bit unhandy) 

-shortcut to toggle trough individual clips within a linked selection.

If i have a clip with a few audio clips attached to it as a linked selection, it would be handy to cycle trough the indidual clips so that i can quickly adjust audio levels.

-increase clip volume while taking the keyframes into account

currently this shortcut just increases the whole clip with all keyframes with it. is there a shorcut that increases the volume only after the last set keyframe?

Thanks!
