Warning: this note describes legacy functionality!
Pre-v8.6.0 functionality is now replaced by Text link creation via the Ziplinks method. The older behaviour is described below for legacy support.
Old Quick links
When typing in the text pane, a new text link can be added by typing two left brackets "[[" and the first character of the destination note's name (and only the first one); multiple letters can be typed to help cut the number of possible matches. Tinderbox will then display a menu of notes whose title starts with that character. Selecting a note from this menu and clicking Return will generate a text link to that note, using the destination note's name as the link's anchor text.
This method is particularly useful for adding references to glossary terms, frequently-used sources, or oft-mentioned people and places; in fact anything where the destination note name makes logical anchor text for the link.
The link generated is always to the original note, even if aliases exist. Previously this was not always the case and an alias might be selected.
