Compositor 0.3 for Windows

Summary

Compositor for Windows 0.3 by Karl Traunmüller 24 September 2025 After a bit of a summer break, the next public prototype of Compositor for Windows is now available! 🎉 What’s New? From a user’s perspective, Compositor for Windows 0.3 will still look very barebones and borderline unusable. And it is, it’s a prototype. But under the hood, this version now has all the important bits in place for… Basic WYSIWYG Editing The app still opens the bundled User Guide on launch, as was the case with milestone 0.2: However, the pages of the document are no longer read-only – there’s now basic WYSIWYG editing capabilities! This means you can place the caret by clicking somewhere in the document, insert text by typing on the keyboard, or deleting characters (or entire selections of text) by using the delete buttons on the keyboard. Don’t expect too much at this point, though. Simple typing and deleting should work, copy & paste and other more complex editing interactions will not yet work. These will be added over time in the upcoming prototypes. Performance also needs to be improved. Basic Mouse Interaction The mouse interaction patterns are basically the same as in the Mac version of the app. A single mouse click will position the caret: A double-click will select the current word: A triple-click will select the current line: A quadruple-click will select the current paragraph: Pressing esc will unfocus the page and hide the caret. Basic Keyboard Navigation This version also brings very basic keyboard navigation. Cursor ←/→ moves the caret by one character, and ctrl + ←/→ moves the caret by one word. Holding shift while moving the caret will extend the selection by one character at a time. Holding both shift and ctrl will extend the selection by one word at a time. Most other keyboard shortcuts (like go up one line, jump to the beginning of a line, go to the previous page, etc) are still missing and will be added over time.
