Enter key for opening file/folder

- enter key to open a file or folder versus renaming it.

Get a key remapping utility, or a hotkey utility, or similar, and tell the utility that when using the Finder, you want <Return> to perform Command-O

I use BetterTouchTool for this kind of activity, as it gives me great control over my trackpad, but it also gives me Windows style snapping, keyboard, mouse, trackpad, touchbar control.

- shift click selects the items from click A to click B

I though it already did that? At least in List mode, if I select A, then Shift-Click on B, I get everything between A and B

If I Command-Click, I can add individual files or folders to the selected items in a non-contiguous manor.

- double tap and move on the touch pad starts a drag selection

I'm not sure about how to solve this. Maybe BetterTouchTool can do it, but I could not find it after a quick search, and I ran out of time to look.

Command-O is the default for opening files and folders but you could set your own key combination in System Preferences>Keyboard>Shortcuts>App Shortcuts.

Shift clicking items from A to B already does select the items in-between.
