Dynamically exposing repetitively used data in a user interface

A non-transitory computer readable medium storing instructions that, when executed by one or more data processing apparatus, cause the one or more data processing apparatus to perform operations comprising, comprising:

• displaying, in a user interface, a keyboard layer of a user interface that includes a keyboard having at least one user interface element configured to receive alpha-numeric user input;
• detecting an initial interaction at a given user interface element that is visually depicted as a symbol other than alpha-numeric characters of the keyboard;
• initiating for display, in response to detecting the initial interaction at the given user interface element, a first portion of a symbol layer in a first area of the user interface while maintaining display of the keyboard layer of the user interface, the symbol layer having at least one user interface element configured to receive a user input for inputting a symbol, the user interface element being selected based on a frequency of use of the symbol;
• detecting a subsequent interaction at the given user interface element while the first portion of the symbol layer is presented in the first area of the user interface;
• increasing, in response to detecting the subsequent interaction at the given user interface element, a size of the symbol layer that is presented in an expanded area of the user interface, wherein the expanded area of the user interface is a larger portion of the user interface than the first area of the user interface in which the first portion of the symbol layer was presented, the expanded area containing additional interface elements configured to receive a user input for inputting a symbol;
• wherein revealing the larger portion of the user interface occludes at least a portion of the keyboard layer.

A system, comprising:

• a data storage device;
• and
• one or more processors configured to interact with the data storage device and execute instructions that cause the one or more processors to perform operations comprising:
• displaying, in a user interface, a keyboard layer of a user interface that includes a keyboard having at least one user interface element configured to receive alpha-numeric user input;
• detecting an initial interaction at a given user interface element that is visually depicted as a symbol other than alpha-numeric characters of the keyboard;
• initiating for display, in response to detecting the initial interaction at the given user interface element, a first portion of a symbol layer in a first area of the user interface while maintaining display of the keyboard layer of the user interface, the symbol layer having at least one user interface element configured to receive a user input for inputting a symbol, the user interface element being selected based on a frequency of use of the symbol;
• detecting a subsequent interaction at the given user interface element while the first portion of the symbol layer is presented in the first area of the user interface;
• increasing, in response to detecting the subsequent interaction at the given user interface element, a size of the symbol layer that is presented in an expanded area of the user interface, wherein the expanded area of the user interface is a larger portion of the user interface than the first area of the user interface in which the first portion of the symbol layer was presented, the expanded area containing additional interface elements configured to receive a user input for inputting a symbol;
• wherein revealing the larger portion of the user interface occludes at least a portion of the keyboard layer.
