Vim Stores the Current Buffer's Path in a Register

Registers in (n)vim contain a lot of super useful data. To wit, the % register stores the path of the current buffer. Some useful things we can do with this register:

• Write the path of the current buffer into the file in Insert Mode: Ctrl + R, %
• If in Normal Mode: "%p
• Copy the path to the clipboard: run the command "let @+=@% (copy the % buffer into the + buffer, which is usually used by the system clipboard), or echo it
