Modifying A Selection Based on Tapping

A computer-readable memory comprising particular instructions that are executable by one or more processors to cause the one or more processors to perform operations, the particular instructions comprising:

• instructions to cause detection of user selection of a first selection boundary and user selection of a second selection boundary through a display surface of a mobile device comprising a plurality of non-display surfaces;
• instructions to cause detection of user selection, through the display surface, of a particular selection boundary from a set comprising the first and second selection boundaries;
• instructions to cause the particular selection boundary to be visually distinguished as a currently selected boundary;
• instructions to cause detection of contact against a non-display surface of the plurality of non-display surfaces;
• and
• instructions to cause the mobile device to move the currently selected boundary in a direction that is based on which particular non-display surface of the plurality of non-display surfaces was contacted.

A computer-readable memory comprising particular instructions that are executable by one or more processors to cause the one or more processors to perform operations, the particular instructions comprising:

• instructions to cause a computing device to receive input that indicates user selection of a block of contiguous entities within a plurality of contiguous entities;
• instructions to cause the computing device to produce output that visually distinguishes, through a visual output device, the block of contiguous from a remainder of the plurality of contiguous entities;
• instructions to cause a computing device to detect a tap against a surface that lacks the visual output device;
• and
• instructions to cause the one or more processors to modify the user selection of the block of contiguous entities based on the detection of the tap.

A mobile device comprising:

• means for detecting a user tap against a part of the mobile device other than a touchscreen of the mobile device;
• means for detecting a direction in which the user tap was administered;
• and
• means for adjusting selection boundaries around currently selected data based on the direction.
