Track View > Utilities menu > Track View Utilities
Track View Utilities displays a dialog listing plug-in Track View utilities. A typical Track View utility displays a modeless dialog (though utilities can be modal) and provides functions that can be applied across multiple selected keys and tracks. You can launch more than one utility by choosing Track View Utilities again.
Randomize Keys: Applies random offset values to Time or Value of selected keys or selected time.
Create Out of Range Keys: Creates keys in the out-of-range time of a track, when the Out of Range type is something other than Constant. Thus, it converts the specified out-of-range area to a keyed area that you can edit and adjust. Select one or more tracks, set the parameters of the utility, and click Apply. In Function Curve display mode, you must select the curve as well as the track.
Select Keys by Time: Selects keys within a specified start and end range of time. Lets you select a large range of time when using the mouse might be awkward--for example, if keys are not visible in the Track View Key window.
Soft Selection Settings Manager: Displays a dialog with controls to adjust the range and falloff of the soft selection of keys in the Dope Sheet and Curve Editor.
Current Value Editor: Provides transform type-in capability from within the Track View modes. Allows you to choose between absolute and relative value editing. The name of the controller appears above the axis choices. This utility launches a floating Current Value window that works for either Dope Sheet — Edit keys mode or Curve Editor. It doesn't work for Edit Ranges.
