6. A system, comprising: at least one computing device; and a plurality of computer instructions executable by the at least one computing device, wherein the plurality of computer instructions, when executed, cause the at least one computing device to at least: designate a series of characters in a text block as being a text unit; bind the series of characters together; encode the text block to generate an encoded text block, the encoded text block comprising a first signal indicating that an entirety of the series of characters in the text unit is to be selected in response to a subset of the series of characters being selected; select, in response to the first signal and at least a portion of the subset of the series of characters being selected, the entirety of the series of characters in the text unit; and encode, in response to an instruction to treat the series of characters as being unbound, the text block to generate a modified encoded text block, wherein the modified encoded text block comprises a second signal indicating that a portion of the series of characters is to be selected in response to the portion of the series of characters being selected.

The system of claim 6 , wherein the plurality of computer instructions further cause the at least one computing device to at least designate an additional series of characters in the text block as an additional text unit.
