I find notepad useful for sanitising clipboard content.
No bold text, italics, bullet points, invisible html.. Just get the text and can copy it to paste again somewhere else.
Ala Cmd+Shift+V on Mac
I always used browser address bar for that. But giving it a second thought, I uploaded the data to Google servers.
Win+r, ctrl+v, ctrl+a, ctrl+x, esc does this without spawning a non ephemeral window
I somewhat regularly use the almost embarrassing key sequence Ctrl-C Ctrl-L Ctrl-V Ctrl-A Ctrl-X to sanitize text I’ve copied from a browser, using the address field to remove any formatting.
