Feature Request: Use custom shortcuts to end the screenshot

[BabyMuu]

I used to be a snipaste user and am used to using CTRL + C to end screenshots and copy pictures to the clipboard (I can only use my left hand to control the start and end screenshots).
But when I use this software, I can only finish the screenshot by double-clicking the selected area (it is difficult to click when the area is too small) or pressing ENTER (right hand is required to complete the screenshot)

I couldn't find a way to change this setting
