Input.ObserverMouse gestures, hotkeys and text expansion for Windows

Draw it. Type it. Done.

Draw a shape with the mouse, press a key combination, or type a short abbreviation. Input.Observer recognizes it, checks which app you're in, and runs the action you set for that app.

01 · What it does

One stroke instead of a trip to the toolbar.

A small native engine does the hooking and matching. The configuration app is separate, so gestures keep working when it's closed.

  • Context01

    Gestures per app

    The same shape can mean different things in a browser, an editor and Explorer. App groups and profiles decide which action wins.

    one Up stroke
    • File ExplorerGo to parent folder
    • Browserno app group, bubbles up to GlobalMaximize or restore window
    • Remote Desktopignore groupIgnored: input goes straight to the app
  • Keyboard02

    Hotkeys and text expansion

    Bind actions to keys as well as strokes, and expand short abbreviations into longer text as you type.

  • Windows03

    Window management

    Move, size, show and hide windows, read and set their values, and run timers with a repeat count.

  • Actions04

    Scripts or steps

    Write actions in a small C-like script, or build them as steps without code. Hand off to AutoHotkey when you need it.

  • Recorder05

    Macro recorder

    Record your mouse and keyboard once, then turn the recording into a snippet for your gestures and hotkeys. Edit it as steps or as a script, and set how fast it replays.

  • Trails06

    Your trail, your look

    Style the built-in gesture trail and hint window, or connect a rendering plugin that draws the stroke however it likes.

Simple mode for most. Scripts for the rest.

Pick from ready-made actions in the configuration app, or open the script editor with completion and inline help for every builtin.
