When iswitchw is triggered, the titles of all visible windows are shown in a popup. Start typing to narrow possible matches -- hit enter at any point to activate the top match. Matches are narrowed using an approximate/'fuzzy' filtering method similar to tools like Ido and CtrlP, filtering is presently handled by tcmatch.dll, originally an extended search module for TotalCommander, it supports multiple search modes, including Regex, fuzzy search, and Pinyin. See documentation in the .ahk file for further info.

Built and tested using AutoHotkeyL v1.1.36.02 on Windows 10 (x64), confirmed working on Windows 11 (x64) as well.

• Capslock activates iswitchw

Chrome and Firefox tabs will appear separately in the list. To enable support for Chrome & Vivaldi, enable the remote debugging protocol by creating a new browser shortcut and append the following to the target field: --remote-debugging-port=9222 you can set the port number to whatever you with, however ensure that they're set to different ports for each browser, then ensure you change the chromeDebugPort and/or vivaldiDebugPort in iswitchw.ahk's configuration section to match.

Firefox tab support is handled by Accv2.ahk and should work out of the box, though it can have a tendency to break after any major UI changes. I don't use it myself so please open an issue if that occurs.

By default, iswitchw is restricted to a single instance and hides itself from the tray. Run the script again at any time to replace the running instance. If you want to quit the script entirely, activate iswitchw with Win + Space and then press Alt + F4.

If you want iswitchw to run when Windows starts, make a shortcut to the iswitchw.ahk file in the folder %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup. See here also.

User configurable options are presented at the top of the ahk script.

• Add a config screen for options, hotkeys, etc.
• See if it's possible to have browser tabs appear in MRU order?
• Maybe AHKv2 rewrite in the future? We'll see...

This fork is a significant departure from previous versions, aside from portions of the function that handles drawing the list view, this is a complete rewrite. See [link] for previous fork history.
