How do I select the characters from cursor position to the beginning/end of line in Ubuntu 18.04 with LXDE?

Post by thosecars82 »

Hello

My laptop's keyboard does not have HOME/END keys. It has a numpad though, that has KP_HOME and KP_END keys on the keys of the numbers 7 and 1.
I have tried to do SHIFT+KP_HOME and SHIFT+KP_END to select the text from the cursor's current position to the beginning/end of the current line but, even though doing that works as expected in Firefox or Abiword, it does not work in all apps. For example, in the text editor app called Pluma, doing that just gets the cursor moving to the beginning/end of the line without selecting anything.

Questions:
1. Do you know how to fix the mentioned shortcuts so that the expected selection takes place in all apps, including Pluma?
2. Do you know the command I should type in lxde-rc.xml (Openobox) to be able to create 2 new shortcuts to select the characters from cursor position to the beginning/end of line?


Thanks in advance

This sounds like an inconsistency, not something you can fix with openbox' rc.xml methinks.

Can you change the behaviour by switching NumLock either on or off?
Or CapsLock?

With NumLock in its original state, please show us output of

Code: Select all

xset q
And a full list of apps that do NOT recognize it.

The output of the command with Numlock off is:
xset q

Capslock value, either ON or OFF, does not change the following behaviours:

1. The behaviour with

Code: Select all

numlock ON
is:

1.a) Pluma and Gnumeric and may be others I did not test yet:
shortcut; behaviour
shift+ Numpad's key 7; cursor gets moved to the beginning of the line without selecting anything.
shift+ Numpad's key 1; cursor gets moved to the end of the line without selecting anything.

1.b) Abiword, Firefox, Composer, etc
shift+ Numpad's key 7; cursor gets moved to the beginning of the line carrying out the expected text selection.
shift+ Numpad's key 1; cursor gets moved to the end of the line carrying out the expected text selection.

1.c) numpad's key 1 without shift types 1
numpad's key 7 without shift types 1

2. The behaviour with

Code: Select all

numlock OFF
is the same in all previously mentioned apps:
a) shift+numpad's key 7: types 7
shift+numpad's key 1: types 1

b) numpad's key 7 without shift moves cursor to the beginning of the line without selecting anyting
numpad's key 1 without shift moves cursor to the end of the line without selecting anyting

I did some testing with Abiword, Gnumeric and Firefox-ESR. It's very confusing, how the behaviour changes when you add Shift (but not Caps Lock).
However, the behaviour seems consistent across all 3 applications.

This is on Archlinux:
FF 78.6.1esr
Gnumeric 1.12.48
Abiword 3.0.4

Running under Xorg 1.20.10

Thanks.

I have found some people that had the same problem as I do:
https://ubuntuforums.org/showthread.php?t=1496421
https://superuser.com/questions/540221/ ... ad-numlock

The following ended up working for me:
Adding "numpad:microsoft", on the blank "Advance setxkbmap Options" of the keyboard layout handler

Thanks
