While their main use seems to be for command line, IMHO some of them (not all) can be also used in the Everything GUI itself.
Please consider providing suitable tokens in a drop-down list that is placed next to the Search bar.
For example, the GUI can have "grab text from clipboard" option, which is equivalent of the #clipboard: token.
Also, please provide a checkbox before the drop-down list.
When this checkbox is unticked, the drop-down list would be disabled, and the search box would accept text.
Each entry in the drop-down list should show the function, not the syntax of the token.
For example, the drop-down list should say Grab text from clipboard instead of #clipboard:.
- If the token has modifiers (/ or #), please provide check boxes so that user can select those modified behaviors.
