WhaTab

About

# Overview

* This extension is a helper tool for Cmd+number (macOS) / Alt+number (Windows/Linux) tab-switching shortcuts.

# How it works

* While you hold the Cmd key (macOS) or the Alt key (Windows/Linux), each tab in the current window temporarily displays a numeric prefix such as [1].

* When you release the key, the tab titles instantly return to normal.

* This makes keyboard-based tab switching faster and more intuitive.

# Key Points

* Numbers are shown only while the key is being held down

* It works like a live guide—nothing is permanently added to the tab titles

* Leaves no visual changes once the key is released

# Limitations / Important Notes

##  Some tabs cannot receive numbers, including:

* Chrome internal pages (e.g., chrome://extensions/)

* Pinned tabs

## Certain special or restricted pages

* Right after installation, the prefix may not appear on the very first Cmd/Alt press until Chrome fully activates the extension.

* Tab numbering may also be skipped if Chrome temporarily restricts access to the tab title for security or technical reasons.
