In one aspect, a virtual input device can be configured by detecting a language identifier associated with a selected data entry field, determining a key mapping corresponding to the detected language identifier, configuring a virtual input device in accordance with the key mapping, wherein the virtual input device includes one or more controls and the key mapping specifies a character corresponding to at least one of the plurality of controls, and presenting the virtual input device to a user. The language identifier can comprise one of an Extensible Markup Language tag and a Hypertext Markup Language tag. Further, user input selecting a second data entry field can be received, wherein a second language identifier is associated with the second data entry field, a second key mapping corresponding to the second language identifier can be determined, and the virtual input device can be configured in accordance with the second key mapping.
