I don’t want to remove “move to onedrive”, just remove the mnemonic M which trolls the mnemonic for “rename”.
Other context items mnemonics can be changed by editing where the ampersand is in the registry key setting up the context entry, but I couldn’t find any key containing that text in a Registry search, and all tips regarding Onedrive in the context menu seem to contain only the program ID number.
(It is causing files to be accidentally moved to onedrive when I want to rename – extremely annoying to have to trawl and move the file back.)
