Set the display speed with the plug-in command "Message weight setting". Each time one character is displayed, it waits for the number of frames specified by the "wait" parameter.
To cancel, set the weight to 0 in Message Weight Settings.
About behavior
Press the button to display the rest of the text at once (maybe unresponsive). However, if there is \. Or \ |, wait as usual.
Note from me @Kupotepo, not the plugin creator: when you open Github, click Raw button on the right top of the screen.
Next, right-click and then select the "Save as..." tab.
Finally, you can select whatever you would like to save.
