Beware that Selenium assumes the zoom level is at 100%! For example, IE will refuse to start (throws an Exception) when the zoom level is different, because the element locating depends on this and if you changed the zoom level, it would click on wrong elements, at wrong places.
Java
You can use the Keys.chord()
method:
WebElement html = driver.findElement(By.tagName("html"));
html.sendKeys(Keys.chord(Keys.CONTROL, Keys.ADD));
Use cautiously and when you're done, reset the zoom back to 100%:
html.sendKeys(Keys.chord(Keys.CONTROL, "0"));
C#
(since I realized C# bindings don't have the Keys.chord()
method)
Or, you can use the Advanced User Interactions API like this (again, Java code, but it should work the same in C#):
WebElement html = driver.findElement(By.tagName("html"));
new Actions(driver)
.sendKeys(html, Keys.CONTROL, Keys.ADD, Keys.NULL)
.perform();
Again, don't forget to reset the zoom afterwards:
new Actions(driver)
.sendKeys(html, Keys.CONTROL, "0", Keys.NULL)
.perform();
Note that the na?ve approach
html.sendKeys(Keys.CONTROL, Keys.ADD);
doesn't work, because the Ctrl key is released in this sendKeys()
method. The WebElement
's sendKeys()
is different from the one in Actions
. Because of this, the Keys.NULL
used in my solution is required.
