Expandomatic

An Obsidian plugin that progressively expands the selection outward, modelled after VSCode's Expand Selection (Alt+Shift+→).

Usage

You'll need to assign the keybindings to Expand Selection and Shrink Selection yourself.

Press ⌃⇧⌘→ (Control+Shift+Command+Right Arrow) repeatedly to grow the selection one unit at a time. Each press wraps the current selection in the next larger syntactic unit. Moving the cursor or changing the selection manually resets the expansion.

Press ⌃⇧⌘← (Control+Shift+Command+Left Arrow) to shrink back through the expansion history one step at a time. Shrink only works while the selection exactly matches the last expanded selection — any manual change to the cursor or selection clears the history.

Expansion levels

Prose (default)

Press Selects
1st Word under cursor
2nd Full URL (if cursor is inside one), otherwise sentence
3rd Sentence
4th Paragraph (blank-line bounded)
5th+ Innermost section (heading + content), then parent sections outward
Last Entire document

Sentence detection uses punctuation heuristics (. ! ? followed by a capital letter or end of text). Single-letter abbreviations like U.S. and Dr. are not treated as sentence boundaries.

Inside a table

Press Selects
1st Word
2nd Cell content (between `
3rd Entire row
4th Entire table

Inside a fenced code block

Press Selects
1st Word
2nd Entire line
3rd Entire fenced block (from ``` to ```)

Inside a math block ($$...$$ or inline $...$)

Inline $...$:

Press Selects
1st Word/token
2nd Term (operator-bounded: + - * / = ^ , ( ) [ ] { })
3rd Entire $...$ (including delimiters)
4th Entire line

Block $$...$$:

Press Selects
1st Word/token
2nd Term
3rd Entire line
4th Entire $$ block
