Open DataGrip, select File->Settings, the current panel displays common settings
Basically, the default settings are enough, and it is very simple to change the settings. The left menu has been classified. The first item is the database-related configuration, and the second item is the configuration appearance. You can modify the theme here, and the key map modification is quick and easy. key, editor configures editor-related settings, where you can modify the editor font, expand the edit item, Editor->Color & Fonts->Font
You need to save the current theme, click save as, give a name, and select the renamed theme to modify it. Here I choose the customary Conurier New font with a size of 14, click apply in the lower right corner, and click OK
Nothing else to set up.
