Anyone knows a way of having a keyboard or touchpad shortcut to move a window from an external screen to the built-in one and vice versa?

BetterTouchTool lets you set up custom keyboard shortcuts to snap windows to the left/right/top/bottom (among other things). You can also create custom gestures, and per-app gestures/shortcuts.

There's nothing built in, but there are third-party programs that provide this functionality. I use the free open source Rectangle which provides shortcuts ctrl-opt-cmd-→ to move to the next display to the right and ctrl-opt-cmd-← to move to the next display to the left. It also provides shortcuts for other positioning of windows (e.g., left/right third/half/two-thirds, top, bottom, etc.).
