show mask action/script

I am trying to create an action or a script that will allow me to reveal a layer mask with a keyboard shortcut.

Normally, in PS CC 2014 I select the layer mask in the layers palette, then hold option and click on the mask icon.

This sequence reveals the layer mask in BW.

I am having trouble recording an action which selects an existing layer mask and then reveals the mask.

The action recording stops after I select the layer mask.

Additionally, I try making a script with the code generated with the script listener plugin. But this also does not work.

Any ideas how to make an action or script that shows the layer mask?
