Delete a macro leaving the argument intact

I’m using TeXstudio and I’m looking for a keyboard shortcut that deletes a generic macro while leaving the macro argument itself intact in the .tex source.

For example I want to make a text normal by removing the boldface macro: from
textbf{generic text} to generic text, all in one simple shortcut.

I’ve seen two similar questions, but they weren’t answering my specific question: one was concerning about the UNIX shell and was labeled as off- topic, the other was about removing the macro effect only in the PDF, while I want to remove the macro in the .tex source.
