Should be a simple one, but I can't work out how to do it. Using WPF4 I want to Bind Ctrl + - to Zoom Out and Ctrl + = to Zoom In:
<KeyBinding Command="{Binding Content.ZoomInCommand}" Gesture="Ctrl+="/>
<KeyBinding Command="{Binding Content.ZoomOutCommand}" Gesture="Ctrl+-"/>
However, I'm getting errors: in the case of Ctrl + =:
未找到请求的值“=”。
有任何想法吗？
Okay - it turns out that the = key does not exist (you can check this through the Key-enumeration - there is no entry for Equal or EqualSign)... I use an international keyboard, so you have to find which key sequence you hit to enter = (for me it's Shift + D0 on a danish keyboard) - and use that key-sequence.
所以你的 XAML 应该是（在丹麦）：
<KeyBinding Command="{Binding Content.ZoomInCommand}" Gesture="Ctrl+Shift+D0"/>
编辑：我相信在美国系统上它是OemPlus键 - 但您可以通过 console-writeline 检查它e.Key按键事件处理程序中的参数）
EDIT2: the - key is OemMinus on my system.
