{{caret_heading}} variable

[Taitava]

I'll write this idea just quickly. This variable would give the heading text based on the caret's current position.

• If the caret is on a heading line, give that line.
• If the caret is not on a heading line, look for the nearest heading above the caret.
• If there is no headings in the file, the variable should be unavailable. I.e. a user could define a default value for this situation. A good example for a default value could be to read another variable: {{title}}.
• If the caret is above all headings, i.e. there's no heading above the caret, the variable should be unavailable, too.

There would be two modes for this variable:

• {{caret_heading:with-hashes}} Would include all hash characters # in the result (and spaces in-between): ### My third level heading
• {{caret_heading:no-hashes}} Would include no hash characters # in the result (and no preceding spaces): My third level heading

Examples:

Gives: Mode: Cooldown first, then execute

Gives: Different debouncing modes
