I'm using protractorfor angular end-to-end aka e2etesting.
我正在使用量角器进行角度端到端又名e2e测试。

How can I send a combination of keys, like Ctrl+A?

It's perfectly possible in Linux and Windows but not in OSX
在 Linux 和 Windows 中完全有可能，但在 OSX 中则不然
var elm = element(by.model('myModel'));
elm.sendKeys(protractor.Key.chord(protractor.Key.CONTROL, "a"));
There is also a non-element variant:
还有一个非元素变体：
browser.actions().keyDown(protractor.Key.CONTROL).sendKeys('a').perform();

If you use protractor-hotkeys, you can use simple hotkey strings (like those from angular-hotkeys) to trigger them in protractor tests.
如果您使用protractor-hotkeys，您可以使用简单的热键字符串（如来自 angular-hotkeys 的那些）在量角器测试中触发它们。
So, this would become:
所以，这将变成：
var hotkeys = require('protractor-hotkeys');
hotkeys.trigger('ctrl+a', { targetElement: element(by.model('myModel')) });

Seems like an old post. But Just sharing a solution worked for me to clear content of Tinymce editor using protractor in MAC.
好像是个老帖子。但只是分享一个解决方案对我有用，可以在 MAC 中使用量角器清除 Tinymce 编辑器的内容。
var body_editor = element(by.id('tinymce'));/*id of body inside iframe*/
body_editor.click().sendKeys(protractor.Key.chord(protractor.Key.COMMAND, "a"));
body_editor.click().sendKeys(protractor.Key.BACK_SPACE);
