3.1.7 Accessibility and helpful functionality

1. Accesskeys

   accesskey is an HTML tag attribute that web pages can set to allow for better accessibility by minimizing movement using simple keybindings.

   Wherever there’s an accesskey, the keys to press are shown after the link or form field, by default as the string " (type ‘k %s’) " (see ‘wwe-accesskey-text’). When there are accesskeys for a page, the word "key" can be shown in the mode-line followed by the number of accesskeys (see ‘wwe-accesskey-mode-line-format’ to change the mode-line text and ‘wwe-display-accesskeys’ to enable this).

   Press ‘k’ (‘wwe-accesskey’) and then the accesskey that’s shown to take action. If the accesskey is for a link URL, you visit the URL. You can use the ‘C-u’ prefix argument to save the file just like when you’re following links.

   If the key is for a form field, the point moves to the field and you’re able to edit the field. Radio and checkbox buttons are toggled on or off depending on the current value. It prompts for text if it’s a text input field, or if it’s a textarea field a textarea buffer opens ready to edit.

   Type ‘k C-h’ to see the accesskey help buffer. It lists all the keys and their respective actions. If the web page has set more than one action for a key, it’s listed here, but pressing the key will only call the first action found. Use ‘TAB’ and ‘<backtab>’ to cycle through the keys and extra actions.

2. Abbreviations

   The full text of abbreviations and acronyms (provided by the <abbr> and <acronym> HTML tags) is inserted after the abbreviation by default. See ‘wwe-render-inserted-abbr-text’ for what to show - the default is " [Abbreviation for %s]". Set ‘wwe-render-insert-abbr-text’ to nil to format the given abbreviation or acronym in the ‘wwe-abbr’ face instead and show the whole word or phrase in the help-echo by typing ‘o l’ with point on the abbreviation or hovering over it with the mouse cursor.

3. Hidden elements

   HTML tags with the attribute aria-hidden="true" indicate elements that should be ignored by screen readers. Set the variable ‘wwe-render-ignore-aria-hidden’ to hide these contents.

4. Reader view

   To view a page in a more readable version, type ‘_ r’ (‘wwe-rerender-readable’) to rerender the page without navigation, headers, footers, and other information that isn’t directly related to the main contents.
