I've recently installed the ConTeXt standalone following the instructions listed below: https://www.contextgarden.net/Ubuntu However, commands as "context" and "mtxrun" only work when executed from terminal. When I specify these commands in a text editor (TeXstudio, Textadept), they just don't work, even with a full path specified. On the contrary, commands as "tex" or "latex" from TeX Live are visible to editors. How to fix that?
