Configure keyboard shortcut to switch tabs with alt + number in jetbrains IDES (PhpStorm)

I want to use the keyboard shortcut: "alt + number" to switch tabs in the jetbrains suit (Pycharm, PhpStorm, etc). For now I do it with the shortcut: "ctrl + alt + arrow right/left ". I know it is not very related to the forum but it is a very useful tool for programming and if you would provide me with that it would be great, anyway Thank you.
