title: Custom inputType / key set for Android soft keyboard
body: <p>I'm looking into changing bits and pieces of Android's input methods, to enter coordinates specifically.</p>
  
  <p>The keys/characters needed are 1234567890.-:
  When choosing numeric signed and decimal I have the first 12 covered, but can't get the : to be included or any other character that can take it's place (perfect would be to have a <kbd>°</kbd> key).</p>
  
  <p>I've now written in input filter that filters those characters: it works but it ain't pretty. The main issue I have is that I can not get the keyboard to open on numbers side instead of the letters side.</p>
  
  <p>Another option that I'd be very interested in would be to amend the existing phone type keypad to include my desired keys. It would remove a lot of clutter and make the remaining keys larger, thus making input easier.</p>
