A keyboard shortcut to add a keyframe to which ever property you have selected.
If I have any property selected in the timeline I would love the ability to use a keyboard shortcut to add a keyframe, I realise you can do this on a small few of the properties, Scale, Position, etc... BUT it would be great to have the ability to do this on which ever property you have selected. If you can already do this, my apologies, but I don't think you can. Please generous Adobe staff can you work your magic. :-)
Thank you for filing this feature request.
To create a keyframe for selected properties, you can choose the Animation > Add Keyframe command. (The name of this command will change if you only have one property selected, ex. Add Opacity Keyframe.)
This command does not have a keyboard shortcut defined by default. However, you can assign a keyboard shortcut for it: choose Edit > Keyboard Shortcuts. More information about assigning keyboard shortcuts can be found here:
Given this information, do you still have a request for us? That is, do you want a shortcut defined by default? If so, which shortcut? (One that is already not in use by After Effects.)
