+** Quick Capture from everywhere
+
+Given the fact that I run Emacs using Emacsclient all the time I though it would be quite helpful to have the ability to capture a to-do from everywhere, e.g. a sudden thought crossing my mind while developing photos or browsing the web. Thanks to the help of an [[https://www.reddit.com/r/emacs/comments/74gkeq/system_wide_org_capture][Reddit post]] by [[https://www.reddit.com/user/lebitso][u/lebitso]] I was able to achieve this goal and I put the code in an extra package that is loaded here.
+
+#+begin_src emacs-lisp
+(use-package org-quick-capture
+  :load-path "packages/")
+#+end_src
+
+To use this, I wrote a small shell script that I'm assigning a keyboard shortcut in my window manager / desktop environment. The shell script essentially runs the following command:
+
+#+begin_src sh
+emacsclient -c -F '(quote (name . "capture"))' -e '(activate-capture-frame)'
+#+end_src

 ** Automatic UUID creation
 
 I am currently exploring the option in Org mode to export a file (or some entries) to an ics-file which I can then in turn import into my calendar. For reliably creating (and most importantly: updating) entries it is necessary that each one has an unique ID. To create a ID for the current entry I could just run =M-x org-id-get-create= and for an entire file execute the following Emacs Lisp ~(org-map-entries 'org-id-get-create)~. Of course this is not an ideal solution. But adding this s-expression to ~org-mode-hook~ would create IDs in all Org file I edit which I also don't like. Since the amount of files I do want the automatic creation is (currently) not that large it is OK for me to do some work on my own, at least if it is only a one time setup.
