disable formatting when using cut and paste

I am using openbox as my window manager. When I copy and paste using Ctrl+c and Ctrl+v from one application into another, it transfers the text formatting together with the text. I have to use plaintext editor in between, so that the formatting is lost. This is pure evil. I assume this was invented by the same people who gave us CapsLock and NumLock, just to drive people crazy and waste millions of man-hours yearly. Anyway, how can I disable this in openbox? I am aware of this [post](https://unix.stackexchange.com/questions/219688/remove-formatting-from-copy-paste-buffer) , but I am not sure how to integrate the suggested solution in my situation. I don't use any external clipboard program, I don't have xclip or xsel installed. I assume the copy/paste functionality is native to openbox? UPDATE: ===== as I explained in the comments, this happens for example when copying from chromium and pasting into firefox. Using Ctrl+Shift+v does seem to work, and pastes text without formatting. However, it is another extra step i need to remember. I have Ctrl+v ingrained in my muscle memory. is it possible to re-define the key shortcut, so that Ctrl+v acts as if i used Ctrl+Shift+v ?
