keyboard shortcut for "select" doesn't work

Hi all:
    I searched on this question, but didn't find anything.... In SW 2015 I mapped the spacebar to the "tools: select" command.  It worked great.  I am now in 2017, and even though I have mapped "tools:select" to the spacebar (or any other key for that matter) it doesn't invoke the "select" command when I enter the keyboard shortcut. I am in a sketch at the time.  It doesn't seem to work for "select all" either.   Is this a change in 2017?

Thanks
