text-editing

A small formatting bar that appears floating over a text selection and disappears when the selection is dropped.

A text area specialised for code, with a gutter of line numbers, syntax colouring and a caret that understands indentation.

The view that puts two versions of a text against each other, side by side or interleaved, marking every line added, removed or changed and aligning what did not.

Text that reads as plain content until you click it, at which point it becomes an input in the same place with save and cancel.

The composer at the bottom of an assistant interface: a growing text area with attachment, model and send controls attached to it.

An editing surface that shows formatting as it will appear rather than as markup, so what the writer sees is close to what readers get.

The strip of formatting controls above or beside an editor, whose buttons report their state from wherever the caret sits.

A field that turns each entry into a removable tag sitting inside the field, with the caret waiting after the last one.

A multi-line text box, usually resizable, for input that will not fit on one line: a comment, a description, an address, a note.

A single line box for typed input, carrying a label, an optional hint, and the error message shown when what was typed does not pass.

Three versions on screen at once, mine, theirs, and the ancestor they both came from, with the result edited underneath so a conflict is decided rather than guessed.

Persisting the reader's work continuously without a save action, usually with a quiet status line reporting when the last save happened.

Completing the reader's text inside the field itself, with the guessed remainder selected so the next keystroke replaces it.

Typing a trigger character inside a text field to open a filtered list of people or objects, inserting the chosen one as a linked token.

Typing a forward slash in a composer to open a menu of actions, where choosing one runs it rather than inserting the words into the message.

Warning the reader that edits will be lost before a navigation or close is allowed to proceed, and offering to save or discard first.

The blinking marker showing where typed text will be inserted, moved by clicking, by arrow keys, or by dragging on touch.

The draggable grip at each end of a touch text selection, used to widen or narrow the range a finger cannot adjust precisely.

Colouring code by what each token is, keyword or string or comment or name, so the structure and the typo are visible before a line has actually been read.
