When lasso-selecting keyframes in the Effect Controls window, select all lassoed keyframes!!!

I know about Pin to Clip Mark, but thanks anyway for the tip. 

Another feature request that goes along with this one is when jumping between keyframes in the Effect Controls Window by clicking on the "Go to Next/Previous Keyframe" buttons, the current clip should remain open, always, even if the keyframe the user navigates to is outside the visible bounds of the clip.  This would make it a lot easier to delete out of bounds keyframes the user no longer wants.  I just requested it.

I agree with your suggestion. I also get frustrated that the last keyframe sometime is on the "next frame" or beyond the edit, so I end up temporarily move the clip up a layer, drag the end of the clip one frame later so I can see the keyframe.

In the meantime, one thing I have been doing is to click on the effects tab pulldown and uncheck "Pin to Clip".

(I wish it defaulted to off or was a preference setting.)

With that turned off I can reduce the effect timeline range so I can see more of the keyframes beyond the clip lenght. 

Very helpful pasting effect with keyframes on differnt lenght clips.

I totally get it. Please be sure to hit the upvote button on your main post as well so we can gain more traction on it. 

Thanks for the reply Rach.  I'm surprised to hear it isn't a bug.  Either way, I'd love to see this fixed since I work a lot with keyframes!
