Note: For format_string text it generally is supposed to work whether or not you type the & 1. Create new course or use existing. Go to Filter settings and check that 'Glossary auto-linking' is set to On. (This might also require a change to system settings if it isn't enabled at site level.) 2. Create new Glossary. Type a name and description and select 'Main glossary' for 'Glossary type', then hit 'Save and display'. 3. Add a new entry. Under Concept type 'D&D'; under Definition type 'Dungeons and Dragons'. Turn on 'This entry should be automatically linked' and save. 4. Add another new entry. Under Concept type 'T&C'; under Definition type 'Terms and conditions'. Turn on the autolink option and save. 4. Back on course page, create a new Page activity. Type a name and description and under Content, type 'What is D&D? How about T&C?'. Save and display. EXPECTED: Both terms should be highlighted as links. The tooltips for both terms should display correctly (without '&' HTML code). When you ctrl-click on both terms to open in a new tab, the relevant glossary entry should display. (NOTE: Due to what appears to be a separate bug in current master, normal left clicks on glossary links do not work on my system anyhow even if they don't have ampersands in, so I'm not including that in this issue.)
