Problem to solve

Currently, when using shortcut "Ctrl + A" in the topography creator, the "About" dialog pops up. Instead, "Ctrl + A" should select all shapes in the topography creator.

When the "Ctrl + A" shortcut works, it would be useful to integrate some rudimentary shortcuts to operate an all selected shapes. For instance:

• "Arrow keys (up, down, left, right)" to move the selected shapes by 0.1 m
• "Arrow keys + Shift" to move the selected shapes by 1.0 m

It would be also useful to move the horizontal and vertical scroll bar via a keyboard shortcut + mouse wheel:

• "Ctrl + mouse wheel" to scroll vertically
• "Shift + mouse wheel" to scroll horizontally

Further details

"Ctrl + A" is a common shortcut for selecting all elements in applications (e.g., MS Word, Gimp etc.). It makes Vadere more intuitive when "Ctrl + A" selects all elements.
