Elementary OS crashes when typing or pressing function keys

In my use with E OS I realized that the function keys did not work, on external keyboards or locked when trying to use them on my own laptop for about 1 or 2 seconds (which is quite annoying).
Researching a little I found that the problem is inherited from Ubuntu, not all cases but in mine, it always happened.
Now I found the solution by running this command on the terminal:

`sudo sed -i 's / modifier_map Mod3 / \ / \ / modifier_map Mod3 / g' / usr / share / X11 / xkb / symbols / us`

It would be nice for this type of problem not to happen by default, and to be corrected in the E OS build.
