In selection is a very common, and useful tool.
You can add it by adding this to your user key bindings. I picked super+alt+s, which follows the rest of the search hotkeys. It overrides the "save all files" command, but only when the search window is open.
Plus, I hardly use that command, and when I need to, I use the command pallete.
{ "keys": ["super+alt+s"], "command": "toggle_in_selection", "context":
[
{ "key": "setting.is_widget", "operator": "equal", "operand": true }
]
}
