I'm building some code completion style text expansion functionality for text areas and inputs in a web application. I'm trying to work out a safe keyboard shortcut for invoking the completion proposals for browsers running on Mac OS X.
I've eliminated some potential candidates:
That leaves Option + Space . I'm aware that may conflict with tools like Ubiquity , but that's something we don't expect our audience to be using.
Are there any conflicts I may have missed with Option+Space? Or do you have a better idea for a keyboard shortcut, and why?
许多Mac OS X应用程序使用Option + Esc进行代码完成或代码提示。
As I recall, Visual Studio and TextMate both use tab to code-complete. In Visual Studio an intellisense menu pops up as you start typing and tab acts as the selection confirmation.
In TextMate, you start typing part of a command then hit tab to activate said command's associated "bundle". The associated bundle typically generates a code snippet and fills in any dynamic parts of the snippet as you type.
Come to think of it, most command lines work this way as well, auto-completing file names and paths when tab is pressed after typing a few characters.
EDIT: You say tabs are needed for field switching in a web interface, but you may want to try intercepting the keyboard event in the textfield, and check if they're started typing a macro. If they have, auto-complete and swallow the key by returning false; if not, simply let the command bubble through.
某些选项卡快捷方式听起来像是最好和最直观的方法-用户应该习惯于'type-tab-type-tab'工作流程-如果只希望是可选的,可以将其与修饰符结合使用。
I discussed these ideas with our design team. One of them suggested using Control + Enter , which is what we decided to go with. This causes forms that only contain a single input field to automatically submit in Firefox, but we deal with that by preventing the default action caused by the event.
I re-assigned the Spotlight command to Command + Shift + Space . This is easily done via Prefrences.App
