# Set Copy-Mode settings
# This requires: brew install reattach-to-user-namespace
#
# Using:
# 1. <prefix> [ to start “copy-mode”
# 2. Move to the text you want to copy using Vim-like key bindings, i.e., k to move up a line, / to search, etc
# 3. v to start selection
# 4. Move to end of text with Vim key-bindings. The selection will be highlighted
# 5. y to copy the highlighted/selected text
#
# Setup 'v' to begin selection as in Vim
bind-key -t vi-copy v begin-selection
bind-key -t vi-copy y copy-pipe "reattach-to-user-namespace pbcopy"

# Update default binding of `Enter` to also use copy-pipe
unbind -t vi-copy Enter
bind-key -t vi-copy Enter copy-pipe "reattach-to-user-namespace pbcopy"
