I assume this is common operation but can't find any information about this. When in copy mode (Ctrl + [) Is there a shortcut to copy the word under the cursor without manually creating the selection?
I've tried to switch to vi-mode and use yw but it doesn't look like it works (in fact, I'm not entirely sure what vi-mode does besides mapping the arrow keys to hjkl).
Any idea how to achieve this?
Edit: As pointed out by @Sebastian Graf, tmux now has a native command: send-keys -X select-word for selecting a word. What follows I leave for posterity ...
bind -n -T copy-mode-vi C-d send-keys b \; send -X begin-selection \; send-keys E
I'm using the above to at least select the current word under the cursor. The shortcut is C-d as inspired by Sublime Text. You will need to have also set set-window-option -g mode-keys vi, but I believe that is default. In vi-mode the b moves the cursor to the beginning of the current word, then it begins selecting with begin-selection, then moves the cursor to the end of the current word with E.
So you could also copy the word with:
bind -n -T copy-mode-vi C-d send-keys b \; send -X begin-selection \; send-keys E \; send -x copy-selection.
I've included all the commands here, because I couldn't find anywhere on the Internet that actually formatted it nicely.
