Selecting
Smart double-click
A double-click does not just grab a word bounded by spaces. It works out what you are pointing at:
Turn it off with Settings → Input → Selection & clipboard → Smart selection.
With it off, double-click falls back to plain word selection using the
word_separators list from config.json — by default:
Copying and pasting
Two settings shape what lands where, both under Settings → Input → Selection
& clipboard:
Copy on select
Selecting with the mouse copies immediately, no ⌘ C. Off by
default.
Trim trailing spaces on copy
Strips trailing whitespace from every copied line — useful when copying out
of a TUI that pads to the pane width. Off by default.
Pasting multiple lines sends them as typed input, exactly as any terminal
does. If the shell supports bracketed paste it will treat the block as one
paste rather than running each line.
