A few crazed tweets about typing on keyboards and keypads

QWERTY

The keyboard layout is

QWERTYUIOP
ASDFGHJKL
ZXCVBNM

and I wondered (aloud on Twitter) what words could be typed using just certain rows.

rupturewort: the longest word that can be written only using the top row on a QWERTY keyboard (although twitterer isn't far behind).

haskalah can be written with the second row on the QWERTY keyboard (and also flagfall). The third row yields no words at all.

Telephone Keypad

The phone keypad looks like:

  1   2   3 
     ABC DEF

  4   5   6
 GHI JKL MNO

  7   8   9
PQRS TUV WXYZ

      0

On a telephone keypad the longest word using the numbers in increasing order is bedfellow (233335569). Without repeats it's bijoux (245689).

Without repeats and only consecutive numbers it's 'glost' (45678), with repeats but consecutive only it's 'begloom' (2345666).

Also, if you type 3333333 on a phone you can spell 'deeded'. 222222 is 'bacaba'

Also the phone keypad version of desentimentalize (3373684636825493) is prime.
