Is there a way to turn the font to bold in the IDE 2.1.1?
Thanks.

Hi @tonytscarpelli. I don't think there is any way to do that. You can change the font though so you might find another font that meets your needs. I'll provide instructions in case you want to try it:

The font can be changed in the IDE's advanced settings:

  1. Open the Command Palette by pressing Ctrl+Shift+P (Command+Shift+P for macOS users).
  2. Select the "Preferences: Open Settings (UI)" command.
  3. A "Preferences" tab will now open in the Arduino IDE main panel. In the "Search Settings" field, type font family
  4. You can now set the fonts by entering a font name in the fields of the settings you are interested in customizing.
    ⓘ This field is a comma-separated lists of font names. The first installed font on the list is used, so a list of multiple fonts provides fallback fonts to use in case the previous ones don't happen to be installed on the system the IDE is running on.
  5. Click the X icon on the "Preferences" tab once you are finished.

The font change will take effect immediately.

Please let me know if you have any questions or problems while customizing the font.

Thanks for the info, but isn't your instructions for VS code?
I'm not using that, just the 2.1.1 IDE.
I have used VS code in the past.
Does doing it there change anything in the 2.1.1 IDE?
Thanks.

No. It is for Arduino IDE 2.x. Please just give it a try to prove it to yourself.

The reason it looks like instructions for VS Code is because the Eclipse Theia framework Arduino IDE is built on is partly based on VS Code, including the user interface design. So you will find some similarities in the user interface of the two applications.

No. Despite the similarities between the user interfaces of Arduino IDE 2.x and VS Code, these are two completely separate applications. Changing the configuration of one application will not have any effect on the other.

Thanks. Couldn't believe it but it worked.
Now I just have to find the right font.
Thanks again.

You are welcome. I'm glad if I was able to be of assistance.

If you would like instructions for determining which fonts are available, you can tell me which operating system you are using.

Just one more question on this.
When using the old IDE we changed the theme file to change all the colors, font, and other things, like bolding the font.
I guess this new IDE works differently.
Is there any instructions anywhere where making changes is explained?
I never saw one in the https://docs.arduino.cc/learn/starting-guide/the-arduino-software-ide link.
Thanks.

Arduino IDE 2.x uses a different theme system. It supports the use of VS Code themes. This is very good news if you are hoping to find a pre-made theme because the tremendous popularity of VS Code means there are thousands of free 3rd party themes available. That is a significant difference from the less than 20 3rd party themes that are available for Arduino IDE 1.x (many of which are unmaintained).

The instructions for finding and installing 3rd party themes are provided here in the advanced usage documentation for Arduino IDE 2.x:

https://github.com/arduino/arduino-ide/blob/main/docs/advanced-usage.md#3rd-party-themes

In case you can't find a pre-made theme that meets your needs, or if you just want to play around with the theme system, it is possible to make your own custom themes. A community member shared some information about doing that in this post:
