Letteral

[A certain effect is achieved] by a letter, by “old man R”, as the master agent is alone named[…]Thus, when Hitchcock repeats certain names and syllabic or even letteral patterns across his films, they appear to link up in active networks[…]Such repetitions isolate specific signifiers—individual letters or letteral clusters, sounds[…], visual “puns”, and citations—which may operate like monadic and nomadic switchboards whose proliferation continues to alter the afterlife not only of the film texts themselves[…]but the literary or cultural mnemonics that they have become embedded in.

In order to avoid the character of being slovenly, always read the lines as composed. This should be done as soon as they are finished and before spacing out; in time the habit will become so fixed, that in spacing out, or even in composing the line, the eye will wander over the words, and detect any letterals.

LITERALS type characters: to read proof for literals is to read letter for letter, watching for proper spelling, punctuation, etc., as well as for typos: formerly spelled letterals.
