Copying and pasting are universally hotkey+c and hotkey+v as an example. Creating a directory is context->new in all cases.
Some changes were weird for a small period of a few days, like when moving from Classic Finder to Mac OS X Finder where the priority of hotkeys for new windows vs. new directories changed. Or when in Windows the address bar got a lower priority than filesystem abstraction of user directories (at which point the purpose got mixed). Same with Gnome2 to Gnome3.
I'm curious to see if it's "hard" as-is, or "hard" when you come from one single environment with a lot of experience that is hard to adapt to something that is not visually identical.
I feel like I try every few years and am unable to do it.
Copy paste also works with right click. To move (a la cut), hold option key.
Also hold option key to see "move" menu option under Edit - Paste (Move)
Edit: yep, it's in the 'common' list: https://support.apple.com/en-us/HT201236
They are also visible by simply clicking a menu or context-menu which shows the shortcuts on the right side at the end. Alternatively the built-in Help is actually usable as well as searching for menu items (click help and the text field will also interactively point to menu items with a big floating arrow when hovering over the search result with your cursor - that functionality works in all native HIG-conform apps, and it is dynamic so it also works when you have stuff like a "history" menu in the menu bar in a browser).
After a couple decades, I'm still holding out for ctrl+x. Someday, someday...
Talking to other Mac users, this seems to be common knowledge - I guess only Windows users moving to OSX should be wary.
It's common knowledge because very single Mac OS X user has lost data due to this bug that Apple has refused to fix for years.
In Explorer, just learn Ctrl-Shift-N.
And alt-up to go to the directory above (cmd-up for Mac). Honestly, using the keyboard for both applications removes a lot of the pain.
