As you can see in the picture.
【1】When I am using prompt of K.M., the process is:
press shortcut for calling up --> show the prompt --> input a text(usually a character) --> pressing enter key means for 'OK' --> FINISH
【2】When I am using prompt of other app, for example, Hammerspoon, the process is:
(Notice that it had already assumed that the prompt would receive a single press for a character)
press shortcut for calling up --> show the prompt --> press a character --> FINISH
Obviously, the process 【2】 is shorter and it is handy for single-hand shortcut/keyboard manipulation.
What I want to do is to create an special version of prompt of K.M. working faster benefiting from process 【2】.
