Cell mode flags

MTBL_CM_FLAG_AUTO_EDIT_MODE	When a key on the keyboard is pressed ( with exception of special keys like [ESC] ), the editing mode begins automatically.
MTBL_CM_FLAG_NO_SELECTION	Cells are never selected. Changing the cell focus by keyboard or mouse doesn't change any selections.
MTBL_CM_FLAG_SINGLE_SELECTION	Only one cell at a time can be selected. When changing the cell focus by keyboard or mouse, the focus cell gets selected and all other selections are removed.

Remarks
MTBL_CM_FLAG_SINGLE_SELECTION and MTBL_CM_FLAG_NO_SELECTION are mutually exclusive.
