I can't use control key on browser! How can I use control key?

I think there is no issue on Mac as command key is separate from control key. But you may have issue on other OS. Wazaterm provides two ways to resolve this.

1. Use binary (Electron app) [MacOS/Windows/Linux/iOS/iPadOS]

You can download binaries from the following list depending on your environment. One drawback of Electron App is just huge..

2. Chrome application

ChromeOS only has option.

For the other OS, as long as chrome is installed, this works. But Chrome webstore was shutdown a few years ago, you need to install the app manually.

1. Download wazaterm.crx from https://github.com/shohey1226/wazaterm-chromeapp/blob/master/dist/wazaterm.crx

2. Open chrome://extensions/ and drag&drop wazaterm.crx to the window

After this, you should be able to access from chrome://apps
