+# How do you surround marked text with a custom snippet?
+
+In order to mark strings as "translatable" in Flask via Flask-WTF, you need to apply special syntax.
+
+This means, e.g. in a Jinja template a string like `Conference` has to be transformed into `{{ _('Conference') }}`.
+
+This is a very tedious work, so I created a shortcut for it.
+
+Add the following lines to your `keybindings.json`:
+
+    "key": "ctrl+shift+alt+0",
+    "command": "editor.action.insertSnippet",
+    "when": "editorHasSelection || editorHasMultipleSelections",
+    "args": {
+        "snippet": "{{ _('${TM_SELECTED_TEXT}') }}"
+    }
+
+I used "ctrl+shift+alt+0" as on the German keyboard the closing curly brace is on the same key as the `0`.
