About FullForms
FullForms is the official Chrome extension for FullForms.com. Search your
private glossaries from the address bar, the right-click menu, or a dedicated
side panel, and fall back to a public FullForms.com lookup when the answer
isn't in your own lists.
WHAT YOU GET
Address bar search. Type "fullforms", press space, then your query. Matching
entries from your glossaries appear inline alongside a "Look up on
FullForms.com" fallback row, so one keystroke pattern always works whether
the answer is in your private lists or the public lookup.
Right-click menu. Select any text on any page and right-click to search your
lists, look it up on FullForms.com, or add the selection as a new entry
without leaving the page.
Side panel. A persistent search surface alongside whatever you are reading.
Shows your recent lists, your favorites, and a quick-add form with
@-mentions, slash commands for callouts, and per-field length cues that
match the web app.
Keyboard shortcuts. Option+Shift+F (Alt+Shift+F on Windows and Linux) opens
the side panel pre-filled with your text selection. Cmd+Shift+Y adds the
selection straight to your most-recently-updated writable list. Both are
remappable from chrome://extensions/shortcuts.
Works offline. Your first sign-in syncs your glossaries to a local cache.
When the network drops, search falls back to the cache automatically with a
clear banner so you always know the source.
Favorites and stars. Tap the heart on any FullForms list page to pin it to
your side panel. Star individual entries from search results.
Workspace scope. Narrow live search to a single workspace from the pill
inside the search box. Defaults to all your workspaces.
Accessible by default. Light and dark themes, three text-size steps in
options, full keyboard navigation, and screen-reader labels on every
interactive control. Honors prefers-reduced-motion.
SIGN IN
You need a free FullForms.com account. The extension uses the same sign-in
you already use on the web, no tokens to copy or paste. Signing out revokes
the access token on the server and clears all local data on the device.
PRIVACY
The extension only reads page text when you explicitly invoke it (right-
click, keyboard shortcut, or opening the side panel). It never reads pages
in the background. All network requests go to list.fullforms.com. Full
