Does anyone know where I need to put this?
;; Allow hash to be entered
(global-set-key (kbd "M-3") '(lambda () (interactive) (insert "#")))
I’ve tried it in dotspacemacs/user-init and dotspacemacs/user-config but it doesn’t work.
On UK keyboards the hash key is ALT + 3 - all I get is it trying to go to window 3, hence trying the code above.
Do you have to press shift+3 on UK keyboards to get #?
If so you probably need to use (kbd "M-#") and Alt+Shift+3. In Emacs land chords involving characters requiring a shift key don’t explicitly mention Shift.
You can also check what key chord Emacs registers by pressing C-h k and then the key chord you want to verify. This also tells you what commands, if any, are currently bound to the chord.
No, Shift+3 gives us the pound symbol £
Alt+3 gives us the # - well usually 
Running C-h k gives me:
M-3 runs the command select-window-3 (found in window-numbering-keymap), which
is an interactive Lisp function in ‘window-numbering.el’.
It is bound to SPC 3, M-m 3, M-3.
(select-window-3 &optional ARG)
Select the window with number 3.
Which is what I am getting. However I just want Alt+3 to give me the # key.
Apparently the code in my previous post works - which makes me think I am putting it in the wrong place?
I’m still getting up to speed with Spacemacs configuration conventions (just started using it), but you might want to try putting it in ~/.spacemacs.d/init.el. Create the directory if it doesn’t already exist.
There isn’t a spacemacs directory just a .spacemacs file..
I did put it in .emacs.d/init.el (also other things I have been trying as well) and nothing I’ve put in there has worked either.
From the docs:
7.5.1 Configuration functions
Three special functions in the ~/.spacemacs file can be used to perform configuration at the beginning and end of Spacemacs loading process:
There wasn’t for me either, but Spacemacs loads its init.el file if it exists.
I’m not sure why it’s not working–maybe somebody else more familiar with Spacemacs and/or UK keyboards has an idea.
I went in their Gitter chat and they told me that emacs keybindings are hierarchical and there are many active at once - generally speaking the ones that are more broadly active have lower priority, so global will have the lowest priority for instance. It starts with highest priority, checks for key, then it goes through the next, and so on.
So the code I actually needed was this:
;; Allow hash to be entered
(define-key window-numbering-keymap (kbd "M-3") nil)
(global-set-key (kbd "M-3") (lambda () (interactive) (insert "#")))
The first line unbinds the higher priority keymap
The second binds what I want in the global keymap
Going back to this… it’s something that’s already built in as well 
Simply use SPC p ' which makes sense, duh!
I currently using diff-hl instead of git-gutter.
it is the only working solution for me, and it has good on-the-fly checking, means that i don’t need to save the file to see the change/diff. It is working well with flycheck as well.
here is my .spacemacs, in case you want to know: https://github.com/dwahyudi/dotfiles/blob/master/spacemacs/.spacemacs
I have a big problem. When using spacemacs on Ubuntu 16.04 it crashes and freezes deadly so often. Usually when I use SPC s s
Any suggestions what to do?
