The Snipping Tool habit, back on your Mac. Capture a region, a window or the whole screen and it opens straight into an editor. Then pin the result on top of your other windows, or lift the text out of the image and paste it as words.
Switched from Windows to Mac and keep reaching for shortcuts that don't exist? Switchover puts them back: Cmd+X/Cmd+V actually cuts and pastes files in Finder, Cmd+Shift+V opens a clipboard history like Win+V with pinning and a Paste Stack for forms, Ctrl+Alt+Delete opens Activity Monitor, Ctrl+Option+Up/Down fills and restores windows, and Ctrl+Option+Shift+S snips to your clipboard. Every shortcut is remappable. No network access, nothing collected. On the Mac App Store.
