When drawing obstacles using WLAN Planner, which of the following keys can be held down to make the obstacles straight lines?

Question

Options

• AAlt
• BTab
• CCtrl
• DShift

• A
  5% (1)
• B
  5% (1)
• C
  15% (3)
• D
  75% (15)

Explanation

Holding Shift while drawing obstacles in WLAN Planner constrains the drawing tool to produce perfectly straight (horizontal or vertical) lines, a behavior consistent with how Shift functions as a constraint modifier across most design, drawing, and mapping software tools. This makes it the correct answer.

The distractors are wrong because Alt typically invokes alternate tool modes or menu access (not line constraint), Tab is used for switching focus between elements or fields, and Ctrl usually triggers actions like copy, undo, or select-all - none of which relate to constraining line direction.

Memory tip: Think "Shift = Straight" - the Shift key is the universal "snap to straight" modifier in virtually all drawing and CAD-style tools, so when you see a question about constraining lines to a straight angle, Shift is almost always the answer.
