Editor UX Fix

한국어

Fold and unfold lines in the Obsidian editor with long-press, clicks, and the mouse wheel.

Features

• Long-press a line to fold or unfold it (0.4 s by default, adjustable in the settings). On a line with no children, the nearest line above that contains it (parent list item or heading) folds. Moving more than 4 px while pressing starts a normal drag selection instead.
• Wheel left of the text steps that line one level at a time: up unfolds, down folds. "Left of the text" means the left margin, indentation, list markers, numbers, and checkboxes. On a heading only the margin counts, not the # (clicking there places the caret as usual). Each step unfolds the shallowest visible folded level, or folds the deepest visible unfolded level, within that line and its children; the last fold step folds the line itself. Nothing happens on a line with no children (its parent and siblings are left alone). The wheel never scrolls there (Shift+wheel still scrolls sideways).
• Click left of the text to fold or unfold that line, like the fold chevron: the caret and focus stay put, and nothing happens on a line with no children. No drag selection starts there.
• Long-press left of the text to fold the line's parent, even if the line has children (the line itself if it has no parent). This folds the block you're in even when its first line is scrolled out of view.
• Hovering left of the text tints the line and its children and shows a pointer cursor (while the left-of-text wheel or click setting is on).
• Fold all / unfold all buttons in the view header (next to the reading view toggle). Fold all folds every level, hidden ones included, so unfolding later still finds the inner levels folded. A button is dimmed when there is nothing to do; both are hidden in reading view.
• When the wheel, a long-press, or a click folds or unfolds, the line under the mouse stays at the same height on screen (or the folded line that now contains it).
• Moving the caret never unfolds anything. CodeMirror still unfolds when the caret lands inside hidden text (for example, from search).
• Each behavior can be turned off in the settings, and the long-press time can be set there. The settings and buttons are in English, or Korean when Obsidian is set to Korean.
• Desktop only.

Folding needs Obsidian's Fold indent and Fold heading settings (Settings → Editor) turned on.
