If this is about saving some typing I recommend you install the excellent tool AutoHotkey. It allows you to insert all sorts of text content with different levels of automation, and in all kinds of programs, not just IFS. You can either bind a keyboard shortcut to insert any text you like (it can be different in different programs as well) or, as I usually do, define an abbreviation that will automatically be expanded to a longer text. As an example, I have an abbreviation defined as ",md" which AutoHotkey immediately expands to my email address.

AutoHotkey can do so much more than to insert text and once you start using it you will never live without it.

If you decide to try it out, report back here and I will show some snippets to be added to its configuration.

Good luck!
