Choose a navigation tool based on what you remember: a title, a phrase, a location or a category.
What do you still remember?
Search has Content, Tool Pages and All segments. Use All words when you remember several words anywhere in a page, or Exact phrase when their order matters. Semantic is available in spaces where meaning-based search has been enabled. Results include excerpts so you can recognize the right page before opening it.
A heading can be linked with [[Page#Heading]]. If a specific paragraph or task needs a durable name, add a unique anchor on the source page:
A passage you want to link to. $reference-point
Link directly to it with [[$reference-point]], or find it by typing $reference in the picker. Anchors must be unique across the space. Markdown/Anchor owns their complete syntax and scope rules. Names and Link explain page naming and link resolution.
Folder/Page creates a page under Folder/ in the tree. A folder gives a page one location. Tags allow multiple categories. Neither is required to write useful pages. If you rename a page, use the page title or supported rename command so SilverBullet can handle incoming links. Renaming files outside SilverBullet needs extra care.
