Language downgrade path

An array of up to eight languages which are used in turn to find the best matching language-specific version of a language-neutral filename. The first language in the path is the language of the current locale. Up to the next three (at indices 1, 2 and 3) can be customised. The remaining languages in the downgrade path are based on a table of language near equivalence which is internal to Symbian.

LDD

A logical device driver. Typically, a single LDD provides functionality common to a class of hardware devices, whereas a PDD supports a specific member of that class.

leave

To leave, is to invoke the function User::Leave(). This causes a return to the current trap harness. A function may also leave because a function it called left.

left adjust

The number of pixels to move before displaying a character.

See also: right adjust  

left text margin

The distance between the leftmost extent of a paragraph and the left edge of the text area. An increasing left text margin width causes a scroll right to occur (text moves leftwards) and a decreasing left text margin width causes a scroll left to occur (text moves rightwards). For an illustration of the left text margin, see Screen layout.
