Dear Amos, Please excuse my ignorance..... I do not know how to get the backtrace of function `handle-switch-frame` When I tried it on the emacs window as M-x handle-switch-frame, it told me that handle-switch-frame must be bound to an event with parameters. If possible, please can you tell me what should I do, and then I shall surely revert back. With all the very best wishes and regards, partha ------ পার্থ প্রতিম ঘোষ [cid:81b610c9-3c4c-41cf-a099-dd9bef3d762b] ________________________________ থেকে: Amos Bird -এর পক্ষ থেকে help-gnu-emacs পাঠান: 24 মার্চ 2019 20.21 প্রতি: Help Gnu Emacs mailing list বিষয়: get backtrace of handle-switch-frame Hello, is it possble to get the backtrace of function `handle-switch-frame` so that I can find out the cause of an unexpected frame switch event? regards, -- Amos Bird amosbird@gmail.com
