Aside from browsers, because I was looking for a place to post the below, there is the popular free utility as AutoHotKey to install by which you create scripts which will do such things as easily remap keys (as I do,for efficiency and do to stiff arthritic fingers) once you find the codes.
In AutoHotKey ^ is ctrl; # is the Win key; + is shift; and ! is alt and > together with a duplicate key differentiates btwn left and right, so that #>+ would mean Win key and right shift.
Each command at below is placed on a separate line.
Accordingly, as regards the issue at hand, my script looked like:
CapsLock::^c
NumLock::Esc
Esc::^v
mbutton::^x
“Return” is placed at the end of the coding.
Thus Caps Lock is remapped to ctrl+c (which I find hard to
accomplish past sessions in Linux);
and Esc to ctrl+v ;
NumLock to Esc
and the middle mouse button to ctrl+x:
Or could change
f2::^v
f4::^x
You could also add a whole lot of Run commands as in:
#9::Run eventvwr.msc
#7::Run control.exe
#8::Run diskmgmt.msc
#9::Run eventvwr.msc
Such are proceeded by Run.
There is also a way to copy and paste as plain text,
Thank God for such options and those who code them.
a new tab to appear next to the active one, rather than at the end of the tab bar (less likely to get lost). Here is how to make New tabs ALWAYS open to the right of the last open tab, not to the right of current tab
Copy and paste
about:config
in the FF address bar, and then the box that appears paste
browser.tabs.insertAfterCurrent and double left click on it to toggle it to True.
Likewise to open a link in a new tab at end of tab bar, paste
browser.tabs.insertRelatedAfterCurrent
and double left click on it to toggle it to True or False (I choose the latter).
Other settings I chose (95.7% sure I got all functions right):
browser.tabs.loadBookmarksInTabs True [load in new tab]
browser.tabs.loadBookmarksInBackground True (does not focus on new tab]
browser.bookmarks.openInTabClosesMenu false [keeps bookmarks open when you click on one]
browser.search.openintab [load in new tab]
browser.urlbar.openintab True [opens link to local files in tab. For Vivaldi, see https://forum.vivaldi.net/post/803019]
layout.css.scrollbar-width-thin.disabled True [more visible]
network.prefetch-next false [prevents loading page links in background]
widget.non-native-theme.win.scrollbar.use-system-size false [
