How to kill all sessions by a single click in PLSQL Developer?

I'm using PL/SQL Developer. Now I need to kill all sessions with a specific status(e.g. INACTIVE) in my oracle database by a single click. Currently I'm killing session one by one. My current strategy is

first GOTO sessions

And then click right button of mouse and select kill row by row:

I've tried both Shift and CTR key to select multiple row at a time but they are failed to select multiple rows.

Killing inactive sessions can be done in 3 clicks with a custom template.

(If you really need a one-click solution you'll probably need to create a custom plugin using Delphi. But that would take a lot of work.)

Once you create and get used to template it will only take a second to run one. First, go to the Templates window, usually in the bottom-left-hand side of the screen. Right-click on the background and select "New Template...". Enter a name for the template.

Now enter this text. It's a PL/SQL block that will kill all inactive sessions.

begin
    for sessions_to_kill in
    (
        select 'alter system kill session '''||sid||','||serial#||',@'||inst_id||''' immediate' v_sql
        from gv$session
        where status = 'INACTIVE'
            --Can't kill your current session.
            and not (sid = sys_context('userenv', 'sid') and inst_id = sys_context('userenv', 'instance'))
    ) loop
        execute immediate sessions_to_kill.v_sql;
    end loop;
end;

To call the template, right-click somewhere in a SQL window, select "Insert Template" and the name. Run the PL/SQL block after it appears in the SQL window.
