Windows和Mac平台在键盘设计和操作约定上存在多处显著差异。1
按键命名和功能的对应关系首先体现在删除键上。Windows的Backspace键对应Mac的Delete键，而Windows的Delete键则对应Mac的Forward Delete键。1修饰键的设置也不尽相同，Windows的⌃Control键功能相当于Mac的⌘Command键，而Mac系统额外提供了⌥Option和⌃Control两个修饰键。1在符号表示方面，Mac采用专门符号标记按键（如⇧、⌘、⌥），Windows通常以文字方式标注（Shift、Ctrl、Alt）。1快捷键的书写格式也有区别，Windows使用加号连接多个按键组合（如Shift+A），而Mac则直接并联显示（如⇧A）。1
特殊字符输入和文本编辑操作也反映了两个平台的差异。Mac通过⌥加按键的组合来输出特殊字符，Windows则通过Alt加数字键盘实现。1在文本字段中，Mac支持Unix/Linux风格的⌃Control快捷键，例如⌃A可将光标移至行首，⌃E移至行尾。1Tab键在两个平台的行为不同，Mac的Tab键仅跳转至需要键盘操作的界面元素，而Windows则跳转所有可交互元素。1Page Up和Page Down键在Mac上仅实现视图滚动而不移动光标位置，在Windows上则直接移动光标。1对于非美国键盘布局，Windows右侧Alt键（AltGr）可输出特定语言的字符，而Mac则使用⌥组合键实现这一功能。1
The keyboard layouts and input mechanisms of Windows and Mac operating systems differ substantially across multiple dimensions, creating distinct user experiences and development considerations for cross-platform applications.1 Key naming conventions diverge significantly, with Windows's Backspace key corresponding to Mac's Delete key, while Windows's Delete key aligns with Mac's Forward Delete function.1 The modifier key arrangements also vary: Windows features the Control key where Mac employs the Command key, though Mac provides both Option and Control keys as additional modifiers.1
Visual and symbolic representation of keyboard commands follows platform-specific conventions.1 Mac uses dedicated symbols to denote keys—such as ⇧ for Shift, ⌘ for Command, and ⌥ for Option—whereas Windows typically employs text labels like Shift, Ctrl, and Alt.1 Shortcut key notation differs as well, with Windows connecting key combinations using plus signs (for example, Shift+A) while Mac notation places symbols directly adjacent to keys (⇧A).1 Text input capabilities distinguish the platforms further: Mac users can press Option plus a key to generate special characters, whereas Windows users accomplish this through Alt combined with numeric keypad entries.1 Additionally, Mac incorporates Unix and Linux-style Control key shortcuts within text fields, allowing operations such as Control+A to move to line beginning and Control+E to reach line end.1
Navigation and interface interaction present further differences.1 Mac's Tab key navigates only to keyboard-operable elements, while Windows Tab cycles through all elements on screen.1 Page Up and Page Down keys behave differently as well—these keys move the cursor in Windows but only scroll the view without repositioning the cursor on Mac.1 On non-US keyboards, Windows provides the right Alt key (AltGr) to input language-specific characters, whereas Mac accomplishes this function through Option key combinations.1
