Absolutely!
First, click on the "More..." button, which will open a whole list of additional buttons. From that list, choose "Bulk changes..."

From there, you will do a few things. Use the screenshot below for a visual explanation of the method I use.

First, I select the triggers on the left that I'd like to move, by clicking on their grey buttons so they turn white/light grey. In this example, I have selected the hip and lHand controls, and you can tell this by the corresponding white dots in the timeline. Next, I will select the exact point (keyframe) where I have dots that I'd like to move. In my example, I am at 1.4 seconds in this animation. I do this step to make it easier to determine exactly where I need to start my cut.
Next, on the right-hand side, I drag the "Selection start at" slider to that time that matches the keyframes I selected in the timeline. If you chose a starting point in the timeline like I did, you can also use the "Start at current time" button below. This will be the starting point of our cut. At this point, I will usually go back over in the timeline and find the keyframe/dot at the end of the sequence, so I can note its time as well, but that's not really shown in the screenshot.
Once you know the end time of the group of keyframes you would like to move, head back over to the right-hand side, and drag the "Selection ends at" slider to that time. This is 3.4 seconds in my example above. If you selected your end keyframe in the timeline as I noted, you can also use the "End at current time" button to move the slider automatically.
Either way, always double check that you have selected the correct group of keyframes. You can do this by looking below the "End at current time" button and seeing what your selection is. In my example above, you can see that Timeline is telling me I have 5 keyframes selected in hipControl, and five keyframes selected in lHandControl, which is based on the controllers I have selected, and my start and end keyframes. If I went over and added the chest control, I would then see "chestControl: 1 keyframe," since there is one keyframe in that selection. If I added the left or right feet, I would not add any additional keyframes, since they have no dots on the timeline in that section of time.
Last, you choose what do do with your bulk selection. The buttons below are pretty self-explanatory. You can cut or copy your selection, and even delete the whole selection. Once you've made your cut or copy, go back to your timeline and choose where you would like to paste them. You could choose a keyframe on the timeline, or you can use the scrubber bar at the top to make sure you've selected the right time. Note: You
must use the Paste button in the Bulk Changes over on the right. You cannot use the Paste (or Cut/Copy) button below the timeline/keyframes.
I hope that helps!
