[[File:Left side of modern US-International keyboard.JPG|thumb|350pxupright 1.25|The {{char|¡}} character is accessible using [[AltGr]]+1 on a modern [[US-International]] keyboard. It is also available using a standardconventional US keyboard by switching to the US-International [[keyboard layout]].]]
{{char|¿}} and {{char|¡}} are available in all [[keyboard layout]]s designed for Spanish-speaking countries. Smart phones typically offer these if you hold down {{keypress|?}} or {{keypress|!}} in the on-screen keyboard. Auto-correct will often turn a normal mark typed at the start of a sentence to the upside-down one.
On systems with an [[AltGr]] key (actual or emulated via [[right Alt key]]) and Extended (or 'International') [[keyboard mapping]] set, the symbols can be accessed directly, though the sequence varies by OS and locality:forand exampleis ondocumented Windowsby andthe [[QWERTY#US-International|US-International]],vendor. useOtherwise {{keypress|AltGr|1}} and {{keypress|AltGr|/}}; onsee [[QWERTY#ChromeOS|ChromeOSUnicode with UK-Extendedinput]], use {{keypress|AltGr|Shift|1}} and {{keypress|AltGr|Shift|-}}.
