## 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 outside comparisons while Insert Tab inserts text outside snippets. In a comparison, Ctrl+i/Tab retains its diff-side focus behavior; use the **Jump forward** palette action or another configured key such as `config.bind "ctrl+y", config.core.jump_forward`. Counts work in either direction, such as `3` followed by Ctrl+o, and stop at the available history.
Normal Ctrl+o moves back through previous locations; Ctrl+i moves forward, including in comparisons. Normal Tab also jumps forward outside comparisons, but cycles panes within comparisons; Shift+Tab cycles backward. The Unix TUI requests disambiguated keyboard events so supporting terminals preserve this distinction. Legacy terminals encode Ctrl+i as Tab and cannot distinguish them; there, use the **Jump forward** palette action or another configured key such as `config.bind "ctrl+y", config.core.jump_forward`. 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 with their tab, pane, and comparison context, not just buffer coordinates. Successful Markdown links, accepted LSP definitions, file-picker opens, `:edit`, `:buffer`, `:bnext`/`:bprev`, and search `/`/`n`/`N` jumps record locations. Back/forward restores the original view, including its comparison file and side; an external LSP definition round-trip does not replace the comparison with an ordinary buffer. Identical buffer/cursor positions in different views remain distinct. Ordinary cursor/word motion, edits, failed navigation, manual tab/pane selection, and jumps that do not change location do not add entries. Traversal itself does not record another jump.
