You can delete single or grouped objects with the [Del] key, or move them with drag and drop or use the keyboard. The cursor keys allow fine positioning in very small steps. However, do not set the snap function in the Format → Grid menu when doing so. You can also cut, copy and paste selected objects by means of the relevant toolbar icons.
Editing selected connecting lines
LOGO!Soft Comfort indicates a selected connecting line by round and square blue handles. You can use the round handles to move the lines at a right angle into the direction in which they extend. You can use the square handles to reassign the beginning or end of a line. Move the lines by dragging the round handles.
Example for the FBD Editor:
If you do not connect a line to a suitable target connector, LOGO!Soft Comfort reconnects it to its initial position after you "release" the mouse button.
