 Space begins a leader sequence in Normal/Visual by default. Press the suffix keys in order; nested prefixes wait without a timeout. The status bar shows the pending sequence. Esc cancels the sequence and pending count without leaving Visual or collapsing carets. See [leader configuration](configuration.md#leader-key) for remapping and declaration rules.

+## Jump history
+
+Normal Ctrl+o moves back through previous locations; Ctrl+i moves forward. Traditional terminals encode Ctrl+i as Tab, so Normal Tab performs the same action while Insert Tab still inserts text. Counts work in either direction, such as `3` followed by Ctrl+o, and stop at the available history.
+
+The session keeps up to 100 primary-caret locations across buffers. Successful Markdown links, accepted LSP definitions, file-picker opens, `:edit`, `:buffer`, `:bnext`/`:bprev`, and search `/`/`n`/`N` jumps record locations. Ordinary cursor/word motion, edits, failed navigation, and jumps that do not change location do not add entries. Traversal itself does not record another jump.
+
+Moving away from a visited point before traversing saves the actual departure position for the return trip. A successful new jump after going back discards the forward branch; failed/no-op jumps preserve it. Closed buffers are skipped rather than reopened. Stored row/grapheme coordinates clamp to the current text after edits; text, dirty state, undo/redo, and file contents are unchanged by traversal. History navigation returns to Normal with one primary caret.
+
+The typed actions are `config.core.jump_back` and `config.core.jump_forward`; custom bindings can use any supported single key or leader sequence. History is in memory for this session only.

 ## Markdown links

 Normal `gf` or `:follow_link` follows the link under the primary caret, without an LSP. Inline links and full/collapsed/shortcut reference links are supported; reference definitions can appear elsewhere in the document. The label or destination can be under the caret. Images, code blocks, and ordinary text are not file links.
