How to create shortcut like in Windows? 
Theres an issue entering and exiting Fullscreen on Deepin 20.4 with Firefox 97. To solve it u need to follow this:

Cannot enter/leave fullscreen
If Firefox detects an EWMH/ICCCM compliant window manager, it will try to send a WM_STATE message to the root window to request Firefox be made to enter (or leave) full-screen mode (as defined by the window manager). Window managers are allowed to ignore it, but if they do, Firefox will assume the request got denied and propagate it to the end user which results in nothing happening. This may result in not being able to full screen a video. A general workaround is to set the
full-screen-api.ignore-widgetstotrueinabout:config.
