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.
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.
