Steps to reproduce the problem:
1. Open the Console and try to type some javascript like data[0]

What is the expected behavior?
Being able to type anything

What went wrong?
In a Spanish keyboard, to type [ or ] we use the combo AltGr (or Ctrl+Alt) with either ` or + and it turns out that these combos are used in dev tools to switch panes, so I need to type the code outside and then paste it in the console.

Did this work before? N/A
