At the description of "hot" keys the letters of the latin alphabet are implied.
Pressing of some hot keys for different modes means activation of different processes. For example, pressing of Insert key in a mode of editing of a vertex means transition into a mode of an insert of vertices, and for modes of creation - activation of dialogue of creation and editing of the metrics of map object.
At start of some modes in the bottom part of a window there is a subsidiary panel on which in the form of functional buttons the activation of corresponding subsidiary modes is appeared.
If necessary it is possible to switch off use of subsidiary panels in properties of map editor.
