Reasoning:

1. Engine functionality already exists - should be fairly easy to expose via SQF
2. With holdAction function the action menu fades out due the standard fadeOut/hide time of action menu being 10s - this cannot be influenced by SQF or config

class Menu
    hideTime = 60;
    quickMenuDelay = 0.5;

This is for the command menu but seems nothing exposed for action menu

There is https://community.bistudio.com/wiki/isActionMenuVisible to check it, but seems no way to open/refresh it.

Suggested commands:

openActionMenu//or show
closeActionMenu
refreshActionMenu
