键盘快捷键允许快速交互，但它们很少被使用，大多数用户严重依赖传统的基于指针的选择来执行大多数命令。我们描述的目标，设计和评估的ExposeHK，一个新的接口机制，旨在增加热键的使用。ExposeHK的四个主要设计目标是：1）使用户能够浏览热键; 2）允许非专家用户发出热键命令，作为专家性能的物理排练; 3）利用空间记忆来帮助非专家用户识别热键;以及4）通过在平面命令层次结构中使用一致的快捷方式来最大限度地提高专家性能。ExposeHK通过在按下修改键时显示覆盖在其关联命令上的热键来支持这些目标。我们在三项实证研究中使用了工具栏、菜单和工具栏来评估ExposeHK。结果表明，参与者使用更多的热键，更经常使用，与其他技术相比，与ExposeHK;他们与ExposeHK比使用指向或其他热键方法更快;他们强烈喜欢ExposeHK。我们的研究表明，ExposeHK可以大大改善用户从“初学者模式”的互动过渡到更高水平的专业知识。
Keyboard shortcuts allow fast interaction, but they are known to be infrequently used, with most users relying heavily on traditional pointer-based selection for most commands. We describe the goals, design, and evaluation of ExposeHK, a new interface mechanism that aims to increase hotkey use. ExposeHK's four key design goals are: 1) enable users to browse hotkeys; 2) allow non-expert users to issue hotkey commands as a physical rehearsal of expert performance; 3) exploit spatial memory to assist non-expert users in identifying hotkeys; and 4) maximise expert performance by using consistent shortcuts in a flat command hierarchy. ExposeHK supports these objectives by displaying hotkeys overlaid on their associated commands when a modifier key is pressed. We evaluated ExposeHK in three empirical studies using toolbars, menus, and a tabbed \'18ribbon' toolbar. Results show that participants used more hotkeys, and used them more often, with ExposeHK than with other techniques; they were faster with ExposeHK than with either pointing or other hotkey methods; and they strongly preferred ExposeHK. Our research shows that ExposeHK can substantially improve the user's transition from a \'18beginner mode' of interaction to a higher level of expertise.
