Sending keyboard shortcuts to chrome with Selenium and Ruby

Question

I'm attempting to launch the devtools in a chrome browser on Linux by using the keyboard shortcuts. Because I'm using Ruby and it does not have a chord method, I've tried the following:

driver.action.key_down(:shift)
             .key_down(:control)
             .send_keys("i")
             .key_up(:shift)
             .key_up(:control)
             .perform

The above code will work in Firefox (as suggested in Key press in (Ctrl+A) Selenium WebDriver), but in chrome, it returns nil but no results occur.

Any advice?

In Selenium I have used :

function key F12.

driver.FindElement(By.XPath("String")).SendKeys(Keys.F12);
