Does that help Under the covers, IDLE is simulating a terminal on top of a Tk widget, which I'm pretty sure is ultimately derived from Text.
The presence of long lines slows down that widget a little bit. And appending to long lines takes longer than appending to short ones. If you really want to understand why this happens, you need to look at the Tcl code underlying the Tk Text widget, which Tkinter.Text is just a thin wrapper around.

hope this fix your issue I've answered this before. It's a little tricky if the caret is not at the end of the textarea:

Hope this helps I have an issue where I'm trying to execute a search query from a textbox and attempting to use enter to initiate the search; however, it doesn't seem to be working. I'm wondering if vb.net/asp.net is doing a postback or something that I'm not aware of. , Try this:
code :
$("#searchbox").keypress(function (e) {
    //alert("this will execute");
    var code = e.keyCode || e.which;
    if (code == 13) {
        alert("this will not execute");
        //window.location.href = "http://www.google.com/";
    }
});
$(document).keydown(function (e) {
    var code = e.keyCode || e.which;
    if (code === 13) {
        e.preventDefault();
    }
});

    if (e.KeyChar == (char) Keys.Return)
    {

this will help The snake code made by dbenham is extremely complex, however since your question is limited to the input mechanism it isn't a problem.
This snake game uses the choice command which only requires a specified key to be pressed and no following key press. Based on what key the user pressed, the variable errorlevel will be changed to the numerical position of that character in the list of options.
code :
CHOICE [/C choices] [/N] [/CS] [/T timeout /D choice] [/M text]

Description:
    This tool allows users to select one item from a list
    of choices and returns the index of the selected choice.

Parameter List:
   /C    choices       Specifies the list of choices to be created.
                       Default list is "YN".

   /N                  Hides the list of choices in the prompt.
                       The message before the prompt is displayed
                       and the choices are still enabled.

   /CS                 Enables case-sensitive choices to be selected.
                       By default, the utility is case-insensitive.

   /T    timeout       The number of seconds to pause before a default
                       choice is made. Acceptable values are from 0 to
                       9999. If 0 is specified, there will be no pause
                       and the default choice is selected.

   /D    choice        Specifies the default choice after nnnn seconds.
                       Character must be in the set of choices specified
                       by /C option and must also specify nnnn with /T.

   /M    text          Specifies the message to be displayed before
                       the prompt. If not specified, the utility
                       displays only a prompt.

   /?                  Displays this help message.
C:\> set errorlevel=-1
C:\> choice /c "YN" /m "Yes or No"
Yes or No: [Y,N]? Y

C:\> Echo %errorlevel%
1

Any of those help Try (keydown.enter)="$event.preventDefault()" as below on that button:
code :
<button mat-raised-button color="primary" 
       type="button"
       (keydown.enter)="$event.preventDefault()" 
       (click)="getCurrency()"
        style="margin-right: 10px;width: 20px">...</button>
