Earlier in SharpShooter Reports there was the possibility to select multiple
controls within a parent container using mouse and keeping the Ctrl button
pressed and dragging to create a rectangular selection. In the new version
of SharpShooter Reports we have replaced this combination of keys
to the Ctrl + Shift. Also there are some hotkeys for selecting.

Ctrl + A	Select all
Ctrl + Shift + A	1. Select all elements in the current container (and child elements)   2. press A – add parent container   3. press A – add all brothers of the parent  (and their child elements)   4. press A – add parent of the parent   5. …
Ctrl + Shift + Mouse (Drag move)	Select all elements that are at least 50% covered by the selection rectangle
Shift + Mouse Click	Add to selection
Ctrl + Mouse Click	Remove selection
