The thing I miss the most on macOS is the equivalent of Shift + Windows key ⊞ + right or left arrow, to move a window from one monitor to the other. This is useful for apps like Excel and MS Word, which can't be dragged if they're maximized.
I have set up a PC and a MacBook to share a screen, keyboard and mouse (KVM switch). If I'm switched to the PC and I want to look at a window on the Mac, and the Mac's window was on the shared monitor previously, there is no way to shift the window to the built-in Retina screen without switching back to the Mac, which has its own set of problems (I can't reliably switch back to the PC, despite using a top-of-the-line Aten KVM).
I have configured Shift-Command ⌘ + ← left arrow to move the window on the Mac, but it only works for apps with a Window option on the menu.
Some of my favourite keystrokes:
Finder:
Command ⌘ + Shift + G: Explicitly paste path
Right-click, Option ⌥ to "Copy as path"
Command ⌘ + Shift + . (period): show hidden files
Command ⌘ + ↑ (up arrow): Go up one level in the directories
I set up shortcuts in magnet app[1]. Cmd+Ctrl+(left/right) moves the window to that half of the current scree, and Cmd+Ctrl+(up/down) moves it across monitors.
You should use an app like Spetacle or Rectangle to achieve this. I use spectacle personally. I can move apps from one monitor to another with command-control-option-arrow_key
No Ctrl + L does not clear the screen. It merely inserts enough blank lines (CR) until the stuff is moved out of sight. It's still there if you scroll up.
