Selecting all text in URL by Ctrl+A doesn't work anymore. Now it brings the cursor to the front.
Try the following (not guaranteed to cover your problem but it's a possibility):
Open your Dash and type in "Tweak" to get to the Tweak Tool (Note that this is not the same as "Ubuntu Tweak") - alternatively, in a console type
gnome-tweak-tool (if it is not currently installed, type
sudo apt-get install gnome-tweak-tool to install it)
Go to the Keyboard & Mouse > Emacs input (formerly Theme section > Gtk+ Keybinding Theme). If this is set to "Emacs", then Ctrl+A will essentially act as if it were the Home key. If this is the case, change the option to "Default" to restore the usual settings.
Alternatively, in Firefox and Google Chrome you can use the shortcut Ctrl+L to select the entire title bar.
There is no Theme section in Ubuntu 18.04 and 20.04.
This works on Ubuntu 20.04.1 LTS.
- Open the dash and type "Tweaks" and open it.
- Select Keyboard & Mouse
- Disable Emacs Input
NB!! Step 2 - The menu is sometimes hidden if the window is too small. Either maximise the window or click the < sign to expand the menu.
If Tweaks is not installed, install it by typing:
sudo apt-get install gnome-tweak-tool
Ctrl A no select all: 1, Home -> Shift End (or reverse) 2, right click or key like right click in image enter image description here -> a, Alt a, ... (to select line "select all")
