[x3d-public] Super simple animations?

Understood that I don't need script. Understand that I suffer from carpal
tunnel and I don't want to waste a lot of time editing duplicate code.
Maybe we can do something like IMPORT/EXPORT or prototypes.
Here's what I have:
DEF JumpAndRunAnimation Group {
children [
DEF JumpAndRunTimer TimeSensor { cycleInterval 3.73 loop TRUE enabled
TRUE }
USE JumpAnimation
USE RunAnimation
]
}
I have also done all the startTime/stopTime stuff necessary to turn off
JumpAndRunTimer in other code. I have also added this:
ROUTE JumpAndRun_Touch.touchTime TO StandTimer.stopTime
ROUTE JumpAndRun_Touch.touchTime TO PitchTimer.stopTime
ROUTE JumpAndRun_Touch.touchTime TO YawTimer.stopTime
ROUTE JumpAndRun_Touch.touchTime TO RollTimer.stopTime
ROUTE JumpAndRun_Touch.touchTime TO WalkTimer.stopTime
ROUTE JumpAndRun_Touch.touchTime TO KickTimer.stopTime
ROUTE JumpAndRun_Touch.touchTime TO StopTimer.stopTime
ROUTE JumpAndRun_Touch.touchTime TO RunTimer.stopTime
ROUTE JumpAndRun_Touch.touchTime TO JumpTimer.stopTime
ROUTE JumpAndRun_Touch.touchTime TO JumpAndRunTimer.startTime
I fully realize that I don't have a working solution yet. I did try
"Enable Multiple Simultaneous Animations" in view3dscene (see image)--there
are a bunch of stopTimes for each touch sensor. Now am working on trying
to combine interpolators without copy/paste and substitution (which I did
try, but I goofed on), which didn't work
I don't know how namespaces, etc. work

I know I am not doing event utilities, but I'm still learning this stuff,
trying not to duplicate a lot of code. I want to understand how to combine
animations like the brain does.
Thanks for your help. I am still ignoring event utilities for now.
