Continuous action/scroll/typing when using shortcut

My current setup is
iMac with Catalina10.15.2.
I have set my Belkin YourType Bluetooth Wireless Keypad for variety shortcuts and added actions.
Actions does work, but it only works single time as if I hit it once.
For example, when I type a letter 't' and hold on it, it continues typing 't' until I release.
Arrow keys for example, When I press ->, the character moves until I release it.
But when I set 'pad #' for anything, it only does one time, not continued.

Any ways that shortcuts can just act like normal keyboards?
