Foldit Wiki

The new interface on the left, contrasted with the original interface on the right.

The new interface completely replaces Foldit's original interface. In the new interface, most Foldit tools are visible onscreen as icons in the action bar. The menus and modes of the original interface are gone.

Some tools in the action bar require a selection, bands, or notes to work. The icons for these tools are "grayed" out until these conditions are met. Hovering over a grayed icon displays the requirements for the tool.

The icons used in the new interface action bar are most the same as the icons in the original interface. Most tools have the same keyboard shortcuts in both the original and new interfaces, with a few key exceptions. Still longtime original interface users have mentioned "muscle memory", meaning they're able to access the tools without thinking about it too much.

The exact appearance of the action bar varies depending on screen size. There may be two rows of icons when the Foldit window is maximized, but these can become three or more rows is the window size is reduced. Icons may appear in different relative positions when the window size changes.

At least in the inital release of the new interface, gray icons don't reveal which tool they are when you hover over them. The hover help only mentions the requirements for activating the tool. The menus in the original interface always identified the tools by name, as well as by icon.

The squirmy nature of the action bar and the lack of names are two major stumbling blocks for users migrating from the original Foldit interface.

See new interface icons for quick guide to the icons in a typical action bar. The image on that page may help in understanding which icon does what in the new interface. The keyboard shortcuts for each icon are also listed.

The wiki also has a detailed explanation of what happened to each original interface menu and mode.



On the menu bar, items the Actions menu have mostly become action bar icons, but some have moved to the vertical menu and even the undo menu. See new interface actions menu for details.


The contents of Undo on the menu bar have moved to the vertical menu. The undo menu also has some new features that migrated from the Actions menu. The Undo menu is now a separate window that can be moved around the screen. The default keyboard shortcut "U" (actually, lowercase "u") shows or hides the undo menu. See new interface undo menu for the slightly new look.


The Modes menu has disappeared; the new interface does not have modes.


The Behavior menu, like the Undo menu, has moved to the vertical menu, and is also moveable window. The default shortcut is "B" (lowercase "b"). The contents of the behavior menu have not changed. See new interface behavior menu for a side-by-side comparison.


Much like Undo and Behavior, the View menu is now accessed through the vertical menu or the "V" (lowercase "v") shortcut. It's another floating window, but it now has a presets mode in addition to the full view options mode. See new interface view menu for the long and the short of it.


Just to keep things interesting, the Menu menu has moved to a different location. It's now activated by clicking on the Foldit icon in the upper left or using the escape key (esc) shortcut. Once again, you can move the resulting window around as desired. See new interface menu menu for the information information on the menu menu.


The cookbook was always a little different than other menus, and it's had the shortest journey. Formerly glued to the left edge of the screen, it's now accessed via the vertical menu — also on the left edge to the screen. The shortcut "C" (lowercase "c") can open or close the cookbook. The cookbook is now a window, and it can be resized vertically as well as horizontally. The function of the cookbook remains unchanged. See new interface cookbook menu for more on the big move.


The Modes menu is gone, and that means that the pie menus and other features of the modes have been adopted by new homes. Most of them have joined the action bar, and now have keyboard shortcuts.


For Pull mode, most of the items from the right click pie menu have become action bar icons. The main exception is the tweak tool, which now requires double-clicking to activate. The Align Guide tool has disappeared; it was hard to find in the selection interface, and now seems to be gone from the new interface.

The good news is that you can pull whenever you feel like in the in the new interface, with no mode switching required. See new interface pull mode for all things pull-related.


Structure mode has also been dispersed to the action bar. The secondary structures tool is now an action bar item, and works with selected segments. The secondary structures tool includes an Auto Structures feature, but the Undo menu also includes an Auto Structures tool that covers everything, regardless of any selection. See new interface structure mode for these structural changes.


Note mode was always the least interesting mode, and its function is now a menu bar item, a little notepad icon with the keyboard shortcut "1". The icon is only active if one or more notes are present. See new interface note mode for detailed notes.


Structure mode was key for design puzzles. It's *two* pie menus have now been jumbled into the action bar, but they've gained keyboard shortcuts. The left click mutate menu is now accessed via the icon with "M" (lowercase "m") shortcut. The "M" shortcut is stolen from the "magic 8-ball" mutate in the original interface, and it's now used for the "pick your acid" mutate". (The magic 8-ball mutate is now the "Y" (lowercase "y") shortcut in the new interface, and can be limited to a selection.) The right click insert/delete menu from structure mode has been reduced to two icons in the action bar. See new interface structure mode for all the mutations.

Ligand Design, Ligand View

On certain puzzles, Ligand Design and Ligand View modes were available. Both these modes opened their own separate windows. Both modes are now available as action bar icons in the new interface. In the new interface, the ligand design and ligand view windows can be open at the same time. A closely related option, MMFF wiggle is also available in the action bar. In the original interface, MMFF wiggle was found in right click pie menu in pull mode, when clicking on a ligand.
