Shortcuts and expansion
How typing a shortcut becomes text, the suggestion list, and the search palette.
Typing a shortcut
Type a snippet's shortcut in any normal text field and it expands into the full content as soon as the shortcut is complete. This works in plain inputs, text areas, rich editors like Gmail, and inside embedded frames.
The suggestion list
Type just the prefix (; by default) and FillKit shows a list of your snippets right under the caret: keep typing to filter, then pick one to insert it. You can turn the bare-prefix list off in Settings.
The search palette
Press Ctrl+Space in any text field and a palette opens over it: type a few letters to search every snippet by name, shortcut or content, hit Enter, and the pick is inserted where you were typing. It is the way in when you remember the snippet but not its shortcut.
Shortcuts without a prefix
A shortcut that does not start with the prefix expands only when you press Tab after typing it. That way plain words can be shortcuts too, without ever firing mid-sentence.
Keeping it quiet
Two ways to stop expansion where you do not want it: flip the master switch in Settings to pause it everywhere, or turn it off per site, from Disabled sites in Settings or straight from the page's right-click menu, e.g. while coding or screen sharing. Autofill has its own per-site switch, so silencing one never silences the other.
