Select text by pressing SHIFT+END

UPDATE

Ok, I have found the below question with the workaround

So it seems that this BUG will not be fixed since it's a java issue.

So the way I'm going to implement it is by detecting the current NUM_LOCK state and then act accordingly. For example:

val = Env.isLockOn(Key.NUM_LOCK)
if val == True:
 print "switching off..."
 type(Key.NUM_LOCK)
else:
 print "already off, doing nothing"

and then:
type (Key.END, KeyModifier.SHIFT | KeyModifier.KEY_CTRL )

or:
type (Key.END, KeyModifier.SHIFT + KeyModifier.CTRL )

To select a string of text, perhaps could you try to use right and left arrow keys, like describe below.
This example is ok for Mac keyboard. You have to adapt it for Windows keyboard.

click("your image or text if ocr is activated")

# Push down the key command with left arrow
keyDown(Key.CMD)
type(Key.LEFT)

# "key command" is still pressed + right arrow is pressed
keyDown(Key.SHIFT)
type(Key.RIGHT)

# The entire the line is selected

# Remove "virtual fingers" from the keyboard :)
keyUp(Key.CMD)
keyUp(Key.SHIFT)

# Validate you've selected the line with a copy of the string and a prompt
type('c', KeyModifier.KEY_CMD)
popup(Env.getClipboard())
