Even with the Qwerty devices now out there, it's still a little tricky to select large chunks of text. So here's a simple way to easily select groups of words quickly.
Step 1: Press and hold on a word
This will select the word that you are holding your digit on in about a second like so:
Step 1a: Keep pressing on the word
Whoa! Another second and it's just selected the whole sentence!
Step: 1b: Keep that finger on!
Another second and now my BlackBerry has selected the rest of the paragraph! That's pretty neat...
Step 1c: Don't let go!
What the...? There's a box around the text and now the screen is scrolling down?! And it just keeps on going until I let go! That's really neat!
OK - so I lied a little bit - it's not 4 steps. It's actually 1 step. Press and hold and the selection magic will happen all by itself.
When you're done you can still use the selection grippers to fine-tune what you've selected. Now go and play!
