Module edit 

Text editing on a TextBody: positions are (paragraph, character offset). Inserting text with \n splits paragraphs; formatting a range splits runs at its ends.

Functions

change_case

Change case: upper, lower, sentence, title, toggle.

char_move

One character left/right across paragraph boundaries.

delete

Delete the range between a and b; returns the caret at the start.

delete_word

Delete a word from pos as Ctrl+Backspace (forward == false) or Ctrl+Delete does in PowerPoint; returns the caret.

end

End of the body.

format

Apply f to the run properties of every run in [a, b). An empty range changes the empty paragraph’s end mark (so typing there picks the formatting up).

format_all

Apply f to every run in the body (and end marks).

insert

Insert text at pos (with props, else the props at pos). \n starts a new paragraph (same level and paragraph props); \u{b} inserts a line break. Returns the caret after it.

insert_body

Insert a formatted body at pos (paste): first paragraph merges into the current one.

next_case

The case Shift+F3 changes s to next, as PowerPoint cycles it: lowercase → Capitalize Each Word → UPPERCASE → lowercase; any other mix goes to UPPERCASE first.

para_down

Ctrl+Down: the start of the next paragraph, or the end of the last one.

para_up

Ctrl+Up: the start of the paragraph, or of the previous one when already there.

props_at

The explicit run properties in effect at pos (the run before the caret, or the end mark).

slice

A formatted copy of the range.

text_range

The text between two positions (\n between paragraphs).

word_at

The word a double-click selects around pos (see words::word_at): the word without its trailing spaces, as PowerPoint selects it.

word_move

Next/previous word stop (Ctrl+Right/Left on Windows, Option+arrows on the Mac). At the end of a paragraph Ctrl+Right goes to the start of the next one; at its start Ctrl+Left goes to the end of the previous one.

Type Aliases

Pos

(paragraph, char offset in the paragraph).
