# Bind 'C-v' for rectangular selection (like Vim's 'Ctrl+v')
# Note: 'rectangle-toggle' is for older tmux versions. 'begin-selection' is more standard now
# and subsequent horizontal/vertical movement after C-v will achieve block.
# However, for explicit block selection in newer tmux, you might use 'rectangle-toggle'
# or a combination. The behavior of C-v can be tricky across versions.
# Let's use the most common one for newer versions:
bind-key -T copy-mode-vi C-v send-keys -X rectangle-toggle
# Or, if rectangle-toggle doesn't work as expected, you might use:
# bind-key -T copy-mode-vi C-v send-keys -X begin-selection # Then move for block


# To copy the selection (yank) with 'y' (like Vim's 'y')
bind-key -T copy-mode-vi 'y' send-keys -X copy-selection-and-cancel

# For pasting with 'p' (optional, as prefix + ] is default)
# bind-key -T copy-mode-vi 'p' send-keys -X paste-buffer
