The LTE is dominated by the language table display. The appearance of this display depends entirely on how you have set display format options, accessible from the editor's option menu.
If you have selected Columns as the display format, there will be column titles above the display. You may adjust column width by dragging the separator bars between these titles.
Whatever the display format, each instance in the table contains three elements: the name of the instance or the number of instances, the string, and any translation that has been entered for the instance.
If the parent project contains more than one instance of the string, the number of instances is displayed instead of an instance name. If the Auto-Open MIE option is checked on the LTE display config window, the MIE will open as soon as you select the multi-instance string. If this option is not checked, the MIE will not open until you select the string and hit Enter or double click it.
To enter translations, simply click anywhere on the item you wish to translate and type it into the floating text box.
