Version: Joplin 1.6.7 (prod, darwin)
OS: MacOS 10.15.7
The Alfred app can automatically replace a keyword with a preset snippet. For example, I can let it immediately replace the word "degree" I just typed with "ºC". But this function works wiredly in the Joplin editor. After I type the keyword, the cursor immediately jumps to the beginning of the note and the snippet is printed there.
Interestingly, there is no problem in the WYSIWYG editor.
