Features for turn of monitors and Hotkey for decrease\increase brightness

[warchiefmarkus]

Hello, for own use i add few functions:

• increase\decrease brightness by hotkey (in my case i use Keychron Q3 Knog - encoder, it generate simple F14 key kodes, but can use any keys combinations)
• turn of (sleep mode\disable power, what only work via DDC/CI protocol on my Samsung monitor) monitor
  I hardcoded some values (keycodes, and order of monitors) but it could be moved to som config.

So its interesting to me, does and how much such features is required by people, to try share my snippets or no ?
