In the mail program, we can use "ctrl -" to decrease the size of of not just email text, but of the program itself. As a user with visual impairments, when I do this accidentally (thinking of programs that allow me to enlarge the text again, I am usually doing this to take a screenshot of a long email) I am forced to uninstall the program and reinstall it to be able to read any text

this is inaccessable and really must be changed, regardless of how many people care about it
