>What steps will reproduce the problem?
1. tap Fn
2.
3.

>What is the expected behavior? What do you see instead?
I noticed that I use Fn for single next key at 99% taps. That means I tap extra 
Fn key in all these cases to switch to normal mode.
I suggest reimplement Fn like any other modifier, Ctrl or Shift:
- if you tap it once then it toggles Fn mode for next single tap an returns to 
normal mode automatically after key tap 
- if you tap it twice then it toggles Fn permanently until next Fn tapped

>What version of Hacker's Keyboard are you using? (See "Debug" section at
the bottom of the app's Settings menu.)
On what phone or tablet?
1.33, huawei mediapad

>If applicable, does this affect the 4-row or 5-row layout, or both? Which
language(s)?
All

>Please provide any additional information below.
For users who got habbit for present behaviour - just another one setting can 
be implemented.

I'll look into adding a setting for this.

FYI, you can use multitouch for the Fn symbol - press and hold Fn, tap the key 
you want, and then let go of Fn. That way, it switches back immediately once 
you've let go of the Fn key.
