<up> key for terminal history

[linqiaozhi]

Thank you for the excellent plugin.

However, when typing in the terminal, pressing the <up> arrow key does not let me see my last command. Instead, it says:

E21: Cannot make changes, 'modifiable' is off

When I disable this plugin, the <up> and <down> keys for scrolling through the history work as normal. Is there a workaround? Notably, the history command still works--so history is being collected, it seems the keymapping is just messed up somehow.

my here works fine. (I'm using hkbb's <Fn>+hjkl + zsh

I haven't map any other keys with plugin (it's really simple you can check the plugin through

check your up mapping with :nmap <up> or terminal settings

[linqiaozhi]

:nmap <up> gives 'No mapping found.'

I have the same issue on multiple terminals across OS X and Linux, all of which are using default settings. And it only happens when the plugin is enabled.

It's not only <up> but any of the arrow keys causes it to exist "insert mode" of the terminal, i.e. as if I hit <esc> or <ctrl>+W+N.

so you met problems on OS X and Linux?
I'm using it in OS X.

You can try uncomment all the mapping / commands in the plugin and see if things are different.

I commented out the following line, and that fixed it.

simpleterm.vim/plugin/simpleterm.vim

Lines 388 to 391 in 669d46d

	" In terminal, use <ESC> to toggle terminal-mode
	" then, use a or i to back to terminal-mode, like insert-mode
	tnor <ESC> <C-\><C-n>

Not sure why--but that is definitely the problem.

Feel free to close, since you can't replicate it. I have a Macbook Pro running High Sierra.

fine
leave it here if someone find it useful
I will remove that line later

Thanks. I had to disable this plugin too because arrow navigation was broken. I'm using OS X 10.14.3 with iTerm 3.2.7 and I'm having the issue as well.

Arrow keys get messed up. Pushing down arrow pulls me out of terminal insert mode into terminal normal mode.
