This extension makes it possible to quickly navigate to a particular folder in the folder pane by clicking on the "QuickNav" button (or pressing F4) and typing the first few letters of the folder name into the Search box that appears. If multiple folders start with the same prefix, you can cycle through them using the up and down arrow keys. Click the "Go" button (or press ENTER) to jump to the selected folder or Esc to cancel the operation. Using the Search method control, The way searching is carried out can be changed to "Match anywhere" to allow searching for text that appears anywhere in the folder name, instead of only at the beginning of the folder name, which is what the default "Match from start" method does. In Thunderbird 121.0 and later, an additional "Go to new tab" button (or pressing CTRL+ENTER) allows the selected folder to be opened in a new mail tab. Note for JAWS users: if you have Forms Mode set to Manual, it is necessary to press ENTER when the QuickNav dialog opens in order to type into the search box. As this is extremely inconvenient, it is recommended that you uncheck the "Disable forms Mode when a new page is loaded" option in JAWS Settings Center. This will cause you to be placed into the edit field immediately when the QuickNav dialog opens. Alternatively, this can also be achieved by setting Forms Mode to anything other than Manual. The verbosity of screen-reader speech can be adjusted using the "Screen-reader verbosity" combo box in the QuickNav dialog.
