Expand description

Passed to various keybinding signals for deleting text.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Chars

Delete characters.

§

WordEnds

Delete only the portion of the word to the left/right of cursor if we’re in the middle of a word.

§

Words

Delete words.

§

DisplayLines

Delete display-lines. Display-lines refers to the visible lines, with respect to the current line breaks. As opposed to paragraphs, which are defined by line breaks in the input.

§

DisplayLineEnds

Delete only the portion of the display-line to the left/right of cursor.

§

ParagraphEnds

Delete to the end of the paragraph. Like C-k in Emacs (or its reverse).

§

Paragraphs

Delete entire line. Like C-k in pico.

§

Whitespace

Delete only whitespace. Like M-\ in Emacs.
